Guns, Germs And Steel Part 14

EUROPEANS COLONIZED AUSTRALIA, rather than Native Australians colonizing Europe, for the same reasons that we have just seen in the case of New Guinea. However, the fates of New Guineans and of Aboriginal Australians were very different. Today, Australia is populated and governed by 20 million non-Aborigines, most of them of European descent, plus increasing numbers of Asians arriving since Australia abandoned its previous White Australia immigration policy in 1973. The Aboriginal population declined by 80 percent, from around 300,000 at the time of European settlement to a minimum of 60,000 in 1921. Aborigines today form an undercla.s.s of Australian society. Many of them live on mission stations or government reserves, or else work for whites as herdsmen on cattle stations. Why did Aborigines fare so much worse than New Guineans?

The basic reason is Australia's suitability (in some areas) for European food production and settlement, combined with the role of European guns, germs, and steel in clearing Aborigines out of the way. While I already stressed the difficulties posed by Australia's climate and soils, its most productive or fertile areas can nevertheless support European farming. Agriculture in the Australian temperate zone is now dominated by the Eurasian temperate-zone staple crops of wheat (Australia's leading crop), barley, oats, apples, and grapes, along with sorghum and cotton of African Sahel origins and potatoes of Andean origins. In tropical areas of northeastern Australia (Queensland) beyond the optimal range of Fertile Crescent crops, European farmers introduced sugarcane of New Guinea origins, bananas and citrus fruit of tropical Southeast Asian origins, and peanuts of tropical South American origins. As for livestock, Eurasian sheep made it possible to extend food production to arid areas of Australia unsuitable for agriculture, and Eurasian cattle joined crops in moister areas.

Thus, the development of food production in Australia had to await the arrival of non-native crops and animals domesticated in climatically similar parts of the world too remote for their domesticates to reach Australia until brought by transoceanic s.h.i.+pping. Unlike New Guinea, most of Australia lacked diseases serious enough to keep out Europeans. Only in tropical northern Australia did malaria and other tropical diseases force Europeans to abandon their 19th-century attempts at settlement, which succeeded only with the development of 20th-century medicine.

Australian Aborigines, of course, stood in the way of European food production, especially because what was potentially the most productive farmland and dairy country initially supported Australia's densest populations of Aboriginal hunter-gatherers. European settlement reduced the number of Aborigines by two means. One involved shooting them, an option that Europeans considered more acceptable in the 19th and late 18th centuries than when they entered the New Guinea highlands in the 1930s. The last large-scale ma.s.sacre, of 31 Aborigines, occurred at Alice Springs in 1928. The other means involved European-introduced germs to which Aborigines had had no opportunity to acquire immunity or to evolve genetic resistance. Within a year of the first European settlers' arrival at Sydney, in 1788, corpses of Aborigines who had died in epidemics became a common sight. The princ.i.p.al recorded killers were smallpox, influenza, measles, typhoid, typhus, chicken pox, whooping cough, tuberculosis, and syphilis.

In these two ways, independent Aboriginal societies were eliminated in all areas suitable for European food production. The only societies that survived more or less intact were those in areas of northern and western Australia useless to Europeans. Within one century of European colonization, 40,000 years of Aboriginal traditions had been mostly swept away.

WE CAN NOW return to the problem that I posed near the beginning of this chapter. How, except by postulating deficiencies in the Aborigines themselves, can one account for the fact that white English colonists apparently created a literate, food-producing, industrial democracy, within a few decades of colonizing a continent whose inhabitants after more than 40,000 years were still nonliterate nomadic hunter-gatherers? Doesn't that const.i.tute a perfectly controlled experiment in the evolution of human societies, forcing us to a simple racist conclusion? return to the problem that I posed near the beginning of this chapter.

Doesn't that const.i.tute a perfectly controlled experiment in the evolution of human societies, forcing us to a simple racist conclusion?

The resolution of this problem is simple. White English colonists did not create a literate, food-producing, industrial democracy in Australia. Instead, they imported all of the elements from outside Australia: the livestock, all of the crops (except macadamia nuts), the metallurgical knowledge, the steam engines, the guns, the alphabet, the political inst.i.tutions, even the germs. All these were the end products of 10,000 years of development in Eurasian environments. By an accident of geography, the colonists who landed at Sydney in 1788 inherited those elements. Europeans have never learned to survive in Australia or New Guinea without their inherited Eurasian technology. Robert Burke and William Wills were smart enough to write, but not smart enough to survive in Australian desert regions where Aborigines were living.

The people who did create a society in Australia were Aboriginal Australians. Of course, the society that they created was not a literate, food-producing, industrial democracy. The reasons follow straightforwardly from features of the Australian environment.

CHAPTER 16

HOW CHINA BECAME CHINESE

IMMIGRATION, AFFIRMATIVE ACTION, MULTILINGUALISM, ethnic diversity-my state of California was among the pioneers of these controversial policies and is now pioneering a backlash against them. A glance into the cla.s.srooms of the Los Angeles public school system, where my sons are being educated, fleshes out the abstract debates with the faces of children. Those children represent over 80 languages spoken in the home, with English-speaking whites in the minority. Every single one of my sons' playmates has at least one parent or grandparent who was born outside the United States; that's true of three of my own sons' four grandparents. But immigration is merely restoring the diversity that America held for thousands of years. Before European settlement, the mainland United States was home to hundreds of Native American tribes and languages and came under control of a single government only within the last hundred years.

In these respects the United States is a thoroughly "normal" country. All but one of the world's six most populous nations are melting pots that achieved political unification recently, and that still support hundreds of languages and ethnic groups. For example, Russia, once a small Slavic state centered on Moscow, did not even begin its expansion beyond the Ural Mountains until A.D. A.D. 1582. From then until the 19th century, Russia proceeded to swallow up dozens of non-Slavic peoples, many of which retain their original language and cultural ident.i.ty. Just as American history is the story of how our continent's expanse became American, Russia's history is the story of how Russia became Russian. India, Indonesia, and Brazil are also recent political creations (or re-creations, in the case of India), home to about 850, 670, and 210 languages, respectively. 1582. From then until the 19th century, Russia proceeded to swallow up dozens of non-Slavic peoples, many of which retain their original language and cultural ident.i.ty. Just as American history is the story of how our continent's expanse became American, Russia's history is the story of how Russia became Russian. India, Indonesia, and Brazil are also recent political creations (or re-creations, in the case of India), home to about 850, 670, and 210 languages, respectively.

The great exception to this rule of the recent melting pot is the world's most populous nation, China. Today, China appears politically, culturally, and linguistically monolithic, at least to laypeople. It was already unified politically in 221 B.C. B.C. and has remained so for most of the centuries since then. From the beginnings of literacy in China, it has had only a single writing system, whereas modern Europe uses dozens of modified alphabets. Of China's 1.2 billion people, over 800 million speak Mandarin, the language with by far the largest number of native speakers in the world. Some 300 million others speak seven other languages as similar to Mandarin, and to each other, as Spanish is to Italian. Thus, not only is China not a melting pot, but it seems absurd to ask how China became Chinese. China has and has remained so for most of the centuries since then.

Thus, not only is China not a melting pot, but it seems absurd to ask how China became Chinese. China has been been Chinese, almost from the beginnings of its recorded history. Chinese, almost from the beginnings of its recorded history.

We take this seeming unity of China so much for granted that we forget how astonis.h.i.+ng it is. One reason why we should not have expected such unity is genetic. While a coa.r.s.e racial cla.s.sification of world peoples lumps all Chinese people as so-called Mongoloids, that category conceals much more variation than the differences between Swedes, Italians, and Irish within Europe. In particular, North and South Chinese are genetically and physically rather different: North Chinese are most similar to Tibetans and Nepalese, while South Chinese are similar to Vietnamese and Filipinos. My North and South Chinese friends can often distinguish each other at a glance by physical appearance: the North Chinese tend to be taller, heavier, paler, with more pointed noses, and with smaller eyes that appear more "slanted" (because of what is termed their epicanthic fold).

North and South China differ in environment and climate as well: the north is drier and colder; the south, wetter and hotter. Genetic differences arising in those differing environments imply a long history of moderate isolation between peoples of North and South China. How did those peoples nevertheless end up with the same or very similar languages and cultures?

China's apparent linguistic near-unity is also puzzling in view of the linguistic disunity of other long-settled parts of the world. For instance, we saw in the last chapter that New Guinea, with less than one-tenth of China's area and with only about 40,000 years of human history, has a thousand languages, including dozens of language groups whose differences are far greater than those among the eight main Chinese languages. Western Europe has evolved or acquired about 40 languages just in the 6,0008,000 years since the arrival of Indo-European languages, including languages as different as English, Finnish, and Russian. Yet fossils attest to human presence in China for over half a million years. What happened to the tens of thousands of distinct languages that must have arisen in China over that long time span?

These paradoxes hint that China too was once diverse, as all other populous nations still are. China differs only by having been unified much earlier. Its "Sinification" involved the drastic h.o.m.ogenization of a huge region in an ancient melting pot, the repopulation of tropical Southeast Asia, and the exertion of a ma.s.sive influence on j.a.pan, Korea, and possibly even India. Hence the history of China offers the key to the history of all of East Asia. This chapter will tell the story of how China did become Chinese.

A CONVENIENT STARTING CONVENIENT STARTING point is a detailed linguistic map of China (see Figure 16.1). A glance at it is an eye-opener to all of us accustomed to thinking of China as monolithic. It turns out that, in addition to China's eight "big" languages-Mandarin and its seven close relatives (often referred to collectively simply as "Chinese"), with between 11 million and 800 million speakers each-China also has over 130 "little" languages, many of them with just a few thousand speakers. All these languages, "big" and "little," fall into four language families, which differ greatly in the compactness of their distributions. point is a detailed linguistic map of China (see Figure 16.1).

All these languages, "big" and "little," fall into four language families, which differ greatly in the compactness of their distributions.

At the one extreme, Mandarin and its relatives, which const.i.tute the Chinese subfamily of the Sino-Tibetan language family, are distributed continuously from North to South China. One could walk through China, from Manchuria in the north to the Gulf of Tonkin in the south, while remaining entirely within land occupied by native speakers of Mandarin and its relatives. The other three families have fragmented distributions, being spoken by "islands" of people surrounded by a "sea" of speakers of Chinese and other language families.

Especially fragmented is the distribution of the Miao-Yao (alias Hmong-Mien) family, which consists of 6 million speakers divided among about five languages, bearing the colorful names of Red Miao, White Miao (alias Striped Miao), Black Miao, Green Miao (alias Blue Miao), and Yao. Miao-Yao speakers live in dozens of small enclaves, all surrounded by speakers of other language families and scattered over an area of half a million square miles, extending from South China to Thailand. More than 100,000 Miao-speaking refugees from Vietnam have carried this language family to the United States, where they are better known under the alternative name of Hmong.

Another fragmented language group is the Austroasiatic family, whose most widely spoken languages are Vietnamese and Cambodian. The 60 million Austroasiatic speakers are scattered from Vietnam in the east to the Malay Peninsula in the south and to northern India in the west. The fourth and last of China's language families is the Tai-Kadai family (including Thai and Lao), whose 50 million speakers are distributed from South China southward into Peninsular Thailand and west to Myanmar (Figure 16.1).

Naturally, Miao-Yao speakers did not acquire their current fragmented distribution as a result of ancient helicopter flights that dropped them here and there over the Asian landscape. Instead, one might guess that they once had a more nearly continuous distribution, which became fragmented as speakers of other language families expanded or induced Miao-Yao speakers to abandon their tongues. In fact, much of that process of linguistic fragmentation occurred within the past 2,500 years and is well doc.u.mented historically. The ancestors of modern speakers of Thai, Lao, and Burmese all moved south from South China and adjacent areas to their present locations within historical times, successively inundating the settled descendants of previous migrations. Speakers of Chinese languages were especially vigorous in replacing and linguistically converting other ethnic groups, whom Chinese speakers looked down upon as primitive and inferior. The recorded history of China's Zhou Dynasty, from 1100 to 221 B.C. B.C., describes the conquest and absorption of most of China's non-Chinese-speaking population by Chinese-speaking states.

We can use several types of reasoning to try to reconstruct the linguistic map of East Asia as of several thousand years ago. First, we can reverse the historically known linguistic expansions of recent millennia. Second, we can reason that modern areas with just a single language or related language group occupying a large, continuous area testify to a recent geographic expansion of that group, such that not enough historical time has elapsed for it to differentiate into many languages. Finally, we can reason conversely that modern areas with a high diversity of languages within a given language family lie closer to the early center of distribution of that language family.

Using those three types of reasoning to turn back the linguistic clock, we conclude that North China was originally occupied by speakers of Chinese and other Sino-Tibetan languages; that different parts of South China were variously occupied by speakers of Miao-Yao, Austroasiatic, and Tai-Kadai languages; and that Sino-Tibetan speakers have replaced most speakers of those other families over South China. An even more drastic linguistic upheaval must have swept over tropical Southeast Asia to the south of China-in Thailand, Myanmar, Laos, Cambodia, Vietnam, and Peninsular Malaysia. Whatever languages were originally spoken there must now be entirely extinct, because all of the modern languages of those countries appear to be recent invaders, mainly from South China or, in a few cases, from Indonesia. Since Miao-Yao languages barely survived into the present, we might also guess that South China once harbored still other language families besides Miao-Yao, Austroasiatic, and Tai-Kadai, but that those other families left no modern surviving languages. As we shall see, the Austronesian language family (to which all Philippine and Polynesian languages belong) may have been one of those other families that vanished from the Chinese mainland, and that we know only because it spread to Pacific islands and survived there.

These language replacements in East Asia remind us of the spread of European languages, especially English and Spanish, into the New World, formerly home to a thousand or more Native American languages. We know from our recent history that English did not come to replace U.S. Indian languages merely because English sounded musical to Indians' ears. Instead, the replacement entailed English-speaking immigrants' killing most Indians by war, murder, and introduced diseases, and the surviving Indians' being pressured into adopting English, the new majority language. The immediate causes of that language replacement were the advantages in technology and political organization, stemming ultimately from the advantage of an early rise of food production, that invading Europeans held over Native Americans. Essentially the same processes accounted for the replacement of Aboriginal Australian languages by English, and of subequatorial Africa's original Pygmy and Khoisan languages by Bantu languages.

Hence East Asia's linguistic upheavals raise a corresponding question: what enabled Sino-Tibetan speakers to spread from North China to South China, and speakers of Austroasiatic and the other original South China language families to spread south into tropical Southeast Asia? Here, we must turn to archaeology for evidence of the technological, political, and agricultural advantages that some Asians evidently gained over other Asians.

AS EVERYWHERE ELSE in the world, the archaeological record in East Asia for most of human history reveals only the debris of hunter-gatherers using unpolished stone tools and lacking pottery. The first East Asian evidence for something different comes from China, where crop remains, bones of domestic animals, pottery, and polished (Neolithic) stone tools appear by around 7500 in the world, the archaeological record in East Asia for most of human history reveals only the debris of hunter-gatherers using unpolished stone tools and lacking pottery. The first East Asian evidence for something different comes from China, where crop remains, bones of domestic animals, pottery, and polished (Neolithic) stone tools appear by around 7500 B.C. B.C. That date is within a thousand years of the beginning of the Neolithic Age and food production in the Fertile Crescent. But because the previous millennium in China is poorly known archaeologically, one cannot decide at present whether the origins of Chinese food production were contemporaneous with those in the Fertile Crescent, slightly earlier, or slightly later. At the least, we can say that China was one of the world's first centers of plant and animal domestication. That date is within a thousand years of the beginning of the Neolithic Age and food production in the Fertile Crescent. But because the previous millennium in China is poorly known archaeologically, one cannot decide at present whether the origins of Chinese food production were contemporaneous with those in the Fertile Crescent, slightly earlier, or slightly later. At the least, we can say that China was one of the world's first centers of plant and animal domestication.

China may actually have encompa.s.sed two or more independent centers of origins of food production. I already mentioned the ecological differences between China's cool, dry north and warm, wet south. At a given lat.i.tude, there are also ecological distinctions between the coastal lowlands and the interior uplands. Different wild plants are native to these disparate environments and would thus have been variously available to incipient farmers in various parts of China. In fact, the earliest identified crops were two drought-resistant species of millet in North China, but rice in South China, suggesting the possibility of separate northern and southern centers of plant domestication.

Chinese sites with the earliest evidence of crops also contained bones of domestic pigs, dogs, and chickens. These domestic animals and crops were gradually joined by China's many other domesticates. Among the animals, water buffalo were most important (for pulling plows), while silkworms, ducks, and geese were others. Familiar later Chinese crops include soybeans, hemp, citrus fruit, tea, apricots, peaches, and pears. In addition, just as Eurasia's east-west axis permitted many of these Chinese animals and crops to spread westward in ancient times, West Asian domesticates also spread eastward to China and became important there. Especially significant western contributions to ancient China's economy have been wheat and barley, cows and horses, and (to a lesser extent) sheep and goats.

As elsewhere in the world, in China food production gradually led to the other hallmarks of "civilization" discussed in Chapters 1114. A superb Chinese tradition of bronze metallurgy had its origins in the third millennium B.C. B.C. and eventually resulted in China's developing by far the earliest cast-iron production in the world, around 500 and eventually resulted in China's developing by far the earliest cast-iron production in the world, around 500 B.C. B.C. The following 1,500 years saw the outpouring of Chinese technological inventions, mentioned in Chapter 13, that included paper, the compa.s.s, the wheelbarrow, and gunpowder. Fortified towns emerged in the third millennium The following 1,500 years saw the outpouring of Chinese technological inventions, mentioned in Chapter 13, that included paper, the compa.s.s, the wheelbarrow, and gunpowder. Fortified towns emerged in the third millennium B.C. B.C., with cemeteries whose great variation between unadorned and luxuriously furnished graves bespeaks emerging cla.s.s differences. Stratified societies whose rulers could mobilize large labor forces of commoners are also attested by huge urban defensive walls, big palaces, and eventually the Grand Ca.n.a.l (the world's longest ca.n.a.l, over 1,000 miles long), linking North and South China. Writing is preserved from the second millennium B.C. B.C. but probably arose earlier. Our archaeological knowledge of China's emerging cities and states then becomes supplemented by written accounts of China's first dynasties, going back to the Xia Dynasty, which arose around 2000 but probably arose earlier. Our archaeological knowledge of China's emerging cities and states then becomes supplemented by written accounts of China's first dynasties, going back to the Xia Dynasty, which arose around 2000 B.C. B.C.

As for food production's more sinister by-product of infectious diseases, we cannot specify where within the Old World most major diseases of Old World origin arose. However, European writings from Roman and medieval times clearly describe the arrival of bubonic plague and possibly smallpox from the east, so these germs could be of Chinese or East Asian origin. Influenza (derived from pigs) is even more likely to have arisen in China, since pigs were domesticated so early and became so important there.

China's size and ecological diversity sp.a.w.ned many separate local cultures, distinguishable archaeologically by their differing styles of pottery and artifacts. In the fourth millennium B.C. B.C. those local cultures expanded geographically and began to interact, compete with each other, and coalesce. Just as exchanges of domesticates between ecologically diverse regions enriched Chinese food production, exchanges between culturally diverse regions enriched Chinese culture and technology, and fierce compet.i.tion between warring chiefdoms drove the formation of ever larger and more centralized states (Chapter 14). those local cultures expanded geographically and began to interact, compete with each other, and coalesce. Just as exchanges of domesticates between ecologically diverse regions enriched Chinese food production, exchanges between culturally diverse regions enriched Chinese culture and technology, and fierce compet.i.tion between warring chiefdoms drove the formation of ever larger and more centralized states (Chapter 14).

While China's north-south gradient r.e.t.a.r.ded crop diffusion, the gradient was less of a barrier there than in the Americas or Africa, because China's north-south distances were smaller; and because China's is transected neither by desert, as is Africa and northern Mexico, nor by a narrow isthmus, as is Central America. Instead, China's long east-west rivers (the Yellow River in the north, the Yangtze River in the south) facilitated diffusion of crops and technology between the coast and inland, while its broad east-west expanse and relatively gentle terrain, which eventually permitted those two river systems to be joined by ca.n.a.ls, facilitated north-south exchanges. All these geographic factors contributed to the early cultural and political unification of China, whereas western Europe, with a similar area but a more rugged terrain and no such unifying rivers, has resisted cultural and political unification to this day.

Some developments spread from south to north in China, especially iron smelting and rice cultivation. But the predominant direction of spread was from north to south. That trend is clearest for writing: in contrast to western Eurasia, which produced a plethora of early writing systems, such as Sumerian cuneiform, Egyptian hieroglyphics, Hitt.i.te, Minoan, and the Semitic alphabet, China developed just a single well-attested writing system. It was perfected in North China, spread and preempted or replaced any other nascent system, and evolved into the writing still used in China today. Other major features of North Chinese societies that spread southward were bronze technology, Sino-Tibetan languages, and state formation. All three of China's first three dynasties, the Xia and Shang and Zhou Dynasties, arose in North China in the second millennium B.C. B.C.

Preserved writings of the first millennium B.C. B.C. show that ethnic Chinese already tended then (as many still do today) to feel culturally superior to non-Chinese "barbarians," while North Chinese tended to regard even South Chinese as barbarians. For example, a late Zhou Dynasty writer of the first millennium show that ethnic Chinese already tended then (as many still do today) to feel culturally superior to non-Chinese "barbarians," while North Chinese tended to regard even South Chinese as barbarians. For example, a late Zhou Dynasty writer of the first millennium B.C. B.C. described China's other peoples as follows: "The people of those five regions-the Middle states and the Rong, Yi, and other wild tribes around them-had all their several natures, which they could not be made to alter. The tribes on the east were called Yi. They had their hair unbound, and tattooed their bodies. Some of them ate their food without its being cooked by fire." The Zhou author went on to describe wild tribes to the south, west, and north as indulging in equally barbaric practices, such as turning their feet inward, tattooing their foreheads, wearing skins, living in caves, not eating cereals, and, of course, eating their food raw. described China's other peoples as follows: "The people of those five regions-the Middle states and the Rong, Yi, and other wild tribes around them-had all their several natures, which they could not be made to alter.

The Zhou author went on to describe wild tribes to the south, west, and north as indulging in equally barbaric practices, such as turning their feet inward, tattooing their foreheads, wearing skins, living in caves, not eating cereals, and, of course, eating their food raw.

States organized by or modeled on that Zhou Dynasty of North China spread to South China during the first millennium B.C. B.C., culminating in China's political unification under the Qin Dynasty in 221 B.C. B.C. Its cultural unification accelerated during that same period, as literate "civilized" Chinese states absorbed, or were copied by, the illiterate "barbarians." Some of that cultural unification was ferocious: for instance, the first Qin emperor condemned all previously written historical books as worthless and ordered them burned, much to the detriment of our understanding of early Chinese history and writing. Those and other draconian measures must have contributed to the spread of North China's Sino-Tibetan languages over most of China, and to reducing the Miao-Yao and other language families to their present fragmented distributions.

Within East Asia, China's head start in food production, technology, writing, and state formation had the consequence that Chinese innovations also contributed heavily to developments in neighboring regions. For instance, until the fourth millennium B.C. B.C. most of tropical Southeast Asia was still occupied by hunter-gatherers making pebble and flake stone tools belonging to what is termed the Hoabinhian tradition, named after the site of Hoa Binh, in Vietnam. Thereafter, Chinese-derived crops, Neolithic technology, village living, and pottery similar to that of South China spread into tropical Southeast Asia, probably accompanied by South China's language families. The historical southward expansions of Burmese, Laotians, and Thais from South China completed the Sinification of tropical Southeast Asia. All those modern peoples are recent offshoots of their South Chinese cousins. most of tropical Southeast Asia was still occupied by hunter-gatherers making pebble and flake stone tools belonging to what is termed the Hoabinhian tradition, named after the site of Hoa Binh, in Vietnam.

The historical southward expansions of Burmese, Laotians, and Thais from South China completed the Sinification of tropical Southeast Asia. All those modern peoples are recent offshoots of their South Chinese cousins.

So overwhelming was this Chinese steamroller that the former peoples of tropical Southeast Asia have left behind few traces in the region's modern populations. Just three relict groups of hunter-gatherers-the Semang Negritos of the Malay Peninsula, the Andaman Islanders, and the Veddoid Negritos of Sri Lanka-remain to suggest that tropical Southeast Asia's former inhabitants may have been dark-skinned and curly-haired, like modern New Guineans and unlike the light-skinned, straight-haired South Chinese and the modern tropical Southeast Asians who are their offshoots. Those relict Negritos of Southeast Asia may be the last survivors of the source population from which New Guinea was colonized. The Semang Negritos persisted as hunter-gatherers trading with neighboring farmers but adopted an Austroasiatic language from those farmers-much as, we shall see, Philippine Negrito and African Pygmy hunter-gatherers adopted languages from their farmer trading partners. Only on the remote Andaman Islands do languages unrelated to the South Chinese language families persist-the last linguistic survivors of what must have been hundreds of now extinct aboriginal Southeast Asian languages.

Even Korea and j.a.pan were heavily influenced by China, although their geographic isolation from it ensured that they did not lose their languages or physical and genetic distinctness, as did tropical Southeast Asia. Korea and j.a.pan adopted rice from China in the second millennium B.C. B.C., bronze metallurgy by the first millennium B.C. B.C., and writing in the first millennium A.D. A.D. China also transmitted West Asian wheat and barley to Korea and j.a.pan. China also transmitted West Asian wheat and barley to Korea and j.a.pan.

In thus describing China's seminal role in East Asian civilization, we should not exaggerate. It is not the case that all cultural advances in East Asia stemmed from China and that Koreans, j.a.panese, and tropical Southeast Asians were noninventive barbarians who contributed nothing. The ancient j.a.panese developed some of the oldest pottery in the world and settled as hunter-gatherers in villages subsisting on j.a.pan's rich seafood resources, long before the arrival of food production. Some crops were probably domesticated first or independently in j.a.pan, Korea, and tropical Southeast Asia.

But China's role was nonetheless disproportionate. For example, the prestige value of Chinese culture is still so great in j.a.pan and Korea that j.a.pan has no thought of discarding its Chinese-derived writing system despite its drawbacks for representing j.a.panese speech, while Korea is only now replacing its clumsy Chinese-derived writing with its wonderful indigenous han'gl alphabet. That persistence of Chinese writing in j.a.pan and Korea is a vivid 20th-century legacy of plant and animal domestication in China nearly 10,000 years ago. Thanks to the achievements of East Asia's first farmers, China became Chinese, and peoples from Thailand to (as we shall see in the next chapter) Easter Island became their cousins.

SPEEDBOAT TO POLYNESIA

PACIFIC ISLAND HISTORY IS ENCAPSULATED FOR ME IN AN incident that happened when three Indonesian friends and I walked into a store in Jayapura, the capital of Indonesian New Guinea. My friends' names were Achmad, Wiwor, and Sauakari, and the store was run by a merchant named Ping Wah. Achmad, an Indonesian government officer, was acting as the boss, because he and I were organizing an ecological survey for the government and had hired Wiwor and Sauakari as local a.s.sistants. But Achmad had never before been in a New Guinea mountain forest and had no idea what supplies to buy. The results were comical. incident that happened when three Indonesian friends and I walked into a store in Jayapura, the capital of Indonesian New Guinea.

Achmad picked up an ax head, causing Wiwor and Sauakari to laugh, because he was holding it upside down. Wiwor and Sauakari showed him how to hold it correctly and to test it. Achmad and Sauakari then looked at Wiwor's bare feet, with toes splayed wide from a lifetime of not wearing shoes. Sauakari picked out the widest available shoes and held them against Wiwor's feet, but the shoes were still too narrow, sending Achmad and Sauakari and Ping Wah into peals of laughter. Achmad picked up a plastic comb with which to comb out his straight, coa.r.s.e black hair. Glancing at Wiwor's tough, tightly coiled hair, he handed the comb to Wiwor. It immediately stuck in Wiwor's hair, then broke as soon as Wiwor pulled on the comb. Everyone laughed, including Wiwor. Wiwor responded by reminding Achmad that he should buy lots of rice, because there would be no food to buy in New Guinea mountain villages except sweet potatoes, which would upset Achmad's stomach-more hilarity.

Despite all the laughter, I could sense the underlying tensions. Achmad was Javan, Ping Wah Chinese, Wiwor a New Guinea highlander, and Sauakari a New Guinea lowlander from the north coast. Javans dominate the Indonesian government, which annexed western New Guinea in the 1960s and used bombs and machine guns to crush New Guinean opposition. Achmad later decided to stay in town and to let me do the forest survey alone with Wiwor and Sauakari. He explained his decision to me by pointing to his straight, coa.r.s.e hair, so unlike that of New Guineans, and saying that New Guineans would kill anyone with hair like his if they found him far from army backup.

Ping Wah had put away his newspaper because importation of Chinese writing is nominally illegal in Indonesian New Guinea. In much of Indonesia the merchants are Chinese immigrants. Latent mutual fear between the economically dominant Chinese and politically dominant Javans erupted in 1966 in a b.l.o.o.d.y revolution, when Javans slaughtered hundreds of thousands of Chinese. As New Guineans, Wiwor and Sauakari shared most New Guineans' resentment of Javan dictators.h.i.+p, but they also scorned each other's groups. Highlanders dismiss lowlanders as effete sago eaters, while lowlanders dismiss highlanders as primitive big-heads, referring both to their ma.s.sive coiled hair and to their reputation for arrogance. Within a few days of my setting up an isolated forest camp with Wiwor and Sauakari, they came close to fighting each other with axes.

Tensions among the groups that Achmad, Wiwor, Sauakari, and Ping Wah represent dominate the politics of Indonesia, the world's fourth-most-populous nation. These modern tensions have roots going back thousands of years. When we think of major overseas population movements, we tend to focus on those since Columbus's discovery of the Americas, and on the resulting replacements of non-Europeans by Europeans within historic times. But there were also big overseas movements long before Columbus, and prehistoric replacements of non-European peoples by other non-European peoples. Wiwor, Achmad, and Sauakari represent three prehistorical waves of people that moved overseas from the Asian mainland into the Pacific. Wiwor's highlanders are probably descended from an early wave that had colonized New Guinea from Asia by 40,000 years ago. Achmad's ancestors arrived in Java ultimately from the South China coast, around 4,000 years ago, completing the replacement there of people related to Wiwor's ancestors. Sauakari's ancestors reached New Guinea around 3,600 years ago, as part of that same wave from the South China coast, while Ping Wah's ancestors still occupy China.

The population movement that brought Achmad's and Sauakari's ancestors to Java and New Guinea, respectively, termed the Austronesian expansion, was among the biggest population movements of the last 6,000 years. One p.r.o.ng of it became the Polynesians, who populated the most remote islands of the Pacific and were the greatest seafarers among Neolithic peoples. Austronesian languages are spoken today as native languages over more than half of the globe's span, from Madagascar to Easter Island. In this book on human population movements since the end of the Ice Ages, the Austronesian expansion occupies a central place, as one of the most important phenomena to be explained. Why did Austronesian people, stemming ultimately from mainland China, colonize Java and the rest of Indonesia and replace the original inhabitants there, instead of Indonesians colonizing China and replacing the Chinese? Having occupied all of Indonesia, why were the Austronesians then unable to occupy more than a narrow coastal strip of the New Guinea lowlands, and why were they completely unable to displace Wiwor's people from the New Guinea highlands? How did the descendants of Chinese emigrants become transformed into Polynesians?

TODAY, THE POPULATION of Java, most other Indonesian islands (except the easternmost ones), and the Philippines is rather h.o.m.ogeneous. In appearance and genes those islands' inhabitants are similar to South Chinese, and even more similar to tropical Southeast Asians, especially those of the Malay Peninsula. Their languages are equally h.o.m.ogeneous: while 374 languages are spoken in the Philippines and western and central Indonesia, all of them are closely related and fall within the same sub-subfamily (Western Malayo-Polynesian) of the Austronesian language family. Austronesian languages reached the Asian mainland on the Malay Peninsula and in small pockets in Vietnam and Cambodia, near the westernmost Indonesian islands of Sumatra and Borneo, but they occur nowhere else on the mainland (Figure 17.1). Some Austronesian words borrowed into English include "taboo" and "tattoo" (from a Polynesian language), "boondocks" (from the Tagalog language of the Philippines), and "amok," "batik," and "orangutan" (from Malay). of Java, most other Indonesian islands (except the easternmost ones), and the Philippines is rather h.o.m.ogeneous.

That genetic and linguistic uniformity of Indonesia and the Philippines is initially as surprising as is the predominant linguistic uniformity of China. The famous Java h.o.m.o erectus h.o.m.o erectus fossils prove that humans have occupied at least western Indonesia for a million years. That should have given ample time for humans to evolve genetic and linguistic diversity and tropical adaptations, such as dark skins like those of many other tropical peoples-but instead Indonesians and Filipinos have light skins. fossils prove that humans have occupied at least western Indonesia for a million years. That should have given ample time for humans to evolve genetic and linguistic diversity and tropical adaptations, such as dark skins like those of many other tropical peoples-but instead Indonesians and Filipinos have light skins.

It is also surprising that Indonesians and Filipinos are so similar to tropical Southeast Asians and South Chinese in other physical features besides light skins and in their genes. A glance at a map makes it obvious that Indonesia offered the only possible route by which humans could have reached New Guinea and Australia 40,000 years ago, so one might naively have expected modern Indonesians to be like modern New Guineans and Australians. In reality, there are only a few New Guinean-like populations in the Philippine / western Indonesia area, notably the Negritos living in mountainous areas of the Philippines. As is also true of the three New Guinean-like relict populations that I mentioned in speaking of tropical Southeast Asia (Chapter 16), the Philippine Negritos could be relicts of populations ancestral to Wiwor's people before they reached New Guinea. Even those Negritos speak Austronesian languages similar to those of their Filipino neighbors, implying that they too (like Malaysia's Semang Negritos and Africa's Pygmies) have lost their original language.

All these facts suggest strongly that either tropical Southeast Asians or South Chinese speaking Austronesian languages recently spread through the Philippines and Indonesia, replacing all the former inhabitants of those islands except the Philippine Negritos, and replacing all the original island languages. That event evidently took place too recently for the colonists to evolve dark skins, distinct language families, or genetic distinctiveness or diversity. Their languages are of course much more numerous numerous than the eight dominant Chinese languages of mainland China, but are no more than the eight dominant Chinese languages of mainland China, but are no more diverse diverse. The proliferation of many similar languages in the Philippines and Indonesia merely reflects the fact that the islands never underwent a political and cultural unification, as did China.

Details of language distributions provide valuable clues to the route of this hypothesized Austronesian expansion. The whole Austronesian language family consists of 959 languages, divided among four subfamilies. But one of those subfamilies, termed Malayo-Polynesian, comprises 945 of those 959 languages and covers almost the entire geographic range of the Austronesian family. Before the recent overseas expansion of Europeans speaking Indo-European languages, Austronesian was the most widespread language family in the world. That suggests that the Malayo-Polynesian subfamily differentiated recently out of the Austronesian family and spread far from the Austronesian homeland, giving rise to many local languages, all of which are still closely related because there has been too little time to develop large linguistic differences. For the location of that Austronesian homeland, we should therefore look not to MalayoPolynesian but to the other three Austronesian subfamilies, which differ considerably more from each other and from Malayo-Polynesian than the sub-subfamilies of Malayo-Polynesian differ among each other.

It turns out that those three other subfamilies have coincident distributions, all of them tiny compared with the distribution of Malayo-Polynesian. They are confined to aborigines of the island of Taiwan, lying only 90 miles from the South China mainland. Taiwan's aborigines had the island largely to themselves until mainland Chinese began settling in large numbers within the last thousand years. Still more mainlanders arrived after 1945, especially after the Chinese Communists defeated the Chinese Nationalists in 1949, so that aborigines now const.i.tute only 2 percent of Taiwan's population. The concentration of three out of the four Austronesian subfamilies on Taiwan suggests that, within the present Austronesian realm, Taiwan is the homeland where Austronesian languages have been spoken for the most millennia and have consequently had the longest time in which to diverge. All other Austronesian languages, from those on Madagascar to those on Easter Island, would then stem from a population expansion out of Taiwan.

WE CAN NOW turn to archaeological evidence. While the debris of ancient village sites does not include fossilized words along with bones and pottery, it does reveal movements of people and cultural artifacts that could be a.s.sociated with languages. Like the rest of the world, most of the present Austronesian realm-Taiwan, the Philippines, Indonesia, and many Pacific islands-was originally occupied by hunter-gatherers lacking pottery, polished stone tools, domestic animals, and crops. (The sole exceptions to this generalization are the remote islands of Madagascar, eastern Melanesia, Polynesia, and Micronesia, which were never reached by hunter-gatherers and remained empty of humans until the Austronesian expansion.) The first archaeological signs of something different within the Austronesian realm come from-Taiwan. Beginning around the fourth millennium turn to archaeological evidence.

The first archaeological signs of something different within the Austronesian realm come from-Taiwan. Beginning around the fourth millennium B.C. B.C., polished stone tools and a distinctive decorated pottery style (so-called Ta-p'en-k'eng pottery) derived from earlier South China mainland pottery appeared on Taiwan and on the opposite coast of the South China mainland. Remains of rice and millet at later Taiwanese sites provide evidence of agriculture.

Ta-p'en-k'eng sites of Taiwan and the South China coast are full of fish bones and mollusk sh.e.l.ls, as well as of stone net sinkers and adzes suitable for hollowing out a wooden canoe. Evidently, those first Neolithic occupants of Taiwan had watercraft adequate for deep-sea fis.h.i.+ng and for regular sea traffic across Taiwan Strait, separating that island from the China coast. Thus, Taiwan Strait may have served as the training ground where mainland Chinese developed the open-water maritime skills that would permit them to expand over the Pacific.

One specific type of artifact linking Taiwan's Ta-p'en-k'eng culture to later Pacific island cultures is a bark beater, a stone implement used for pounding the fibrous bark of certain tree species into rope, nets, and clothing. Once Pacific peoples spread beyond the range of wool-yielding domestic animals and fiber plant crops and hence of woven clothing, they became dependent on pounded bark "cloth" for their clothing. Inhabitants of Rennell Island, a traditional Polynesian island that did not become Westernized until the 1930s, told me that Westernization yielded the wonderful side benefit that the island became quiet. No more sounds of bark beaters everywhere, pounding out bark cloth from dawn until after dusk every day!

Within a millennium or so after the Ta-p'en-k'eng culture reached Taiwan, archaeological evidence shows that cultures obviously derived from it spread farther and farther from Taiwan to fill up the modern Austronesian realm (Figure 17.2). The evidence includes ground stone tools, pottery, bones of domestic pigs, and crop remains. For example, the decorated Ta-p'en-k'eng pottery on Taiwan gave way to undecorated plain or red pottery, which has also been found at sites in the Philippines and on the Indonesian islands of Celebes and Timor. This cultural "package" of pottery, stone tools, and domesticates appeared around 3000 B.C. B.C. in the Philippines, around 2500 in the Philippines, around 2500 B.C. B.C. on the Indonesian islands of Celebes and North Borneo and Timor, around 2000 on the Indonesian islands of Celebes and North Borneo and Timor, around 2000 B.C. B.C. on Java and Sumatra, and around 1600 on Java and Sumatra, and around 1600 B.C. B.C. in the New Guinea region. There, as we shall see, the expansion a.s.sumed a speedboat pace, as bearers of the cultural package raced eastward into the previously uninhabited Pacific Ocean beyond the Solomon Archipelago.

Astonis.h.i.+ngly, it also swept westward across the Indian Ocean to the east coast of Africa, resulting in the colonization of the island of Madagascar.

At least until the expansion reached coastal New Guinea, travel between islands was probably by double-outrigger sailing canoes, which are still widespread throughout Indonesia today. That boat design represented a major advance over the simple dugout canoes prevalent among traditional peoples living on inland waterways throughout the world. A dugout canoe is just what its name implies: a solid tree trunk "dug out" (that is, hollowed out), and its ends shaped, by an adze. Since the canoe is as round-bottomed as the trunk from which it was carved, the least imbalance in weight distribution tips the canoe toward the overweighted side. Whenever I've been paddled in dugouts up New Guinea rivers by New Guineans, I have spent much of the trip in terror: it seemed that every slight movement of mine risked capsizing the canoe and spilling out me and my binoculars to commune with crocodiles. New Guineans manage to look secure while paddling dugouts on calm lakes and rivers, but not even New Guineans can use a dugout in seas with modest waves. Hence some stabilizing device must have been essential not only for the Austronesian expansion through Indonesia but even for the initial colonization of Taiwan.

The solution was to lash two smaller logs ("outriggers") parallel to the hull and several feet from it, one on each side, connected to the hull by poles lashed perpendicular to the hull and outriggers. Whenever the hull starts to tip toward one side, the buoyancy of the outrigger on that side prevents the outrigger from being pushed under the water and hence makes it virtually impossible to capsize the vessel. The invention of the double-outrigger sailing canoe may have been the technological breakthrough that triggered the Austronesian expansion from the Chinese mainland.

TWO STRIKING COINCIDENCES between archaeological and linguistic evidence support the inference that the people bringing a Neolithic culture to Taiwan, the Philippines, and Indonesia thousands of years ago spoke Austronesian languages and were ancestral to the Austronesian speakers still inhabiting those islands today. First, both types of evidence point unequivocally to the colonization of Taiwan as the first stage of the expansion from the South China coast, and to the colonization of the Philippines and Indonesia from Taiwan as the next stage. If the expansion had proceeded from tropical Southeast Asia's Malay Peninsula to the nearest Indonesian island of Sumatra, then to other Indonesian islands, and finally to the Philippines and Taiwan, we would find the deepest divisions (reflecting the greatest time depth) of the Austronesian language family among the modern languages of the Malay Peninsula and Sumatra, and the languages of Taiwan and the Philippines would have differentiated only recently within a single subfamily. Instead, the deepest divisions are in Taiwan, and the languages of the Malay Peninsula and Sumatra fall together in the same sub-sub-subfamily: a recent branch of the Western Malayo-Polynesian sub-subfamily, which is in turn a fairly recent branch of the Malayo-Polynesian subfamily. Those details of linguistic relations.h.i.+ps agree perfectly with the archaeological evidence that the colonization of the Malay Peninsula was recent, and followed rather than preceded the colonization of Taiwan, the Philippines, and Indonesia. between archaeological and linguistic evidence support the inference that the people bringing a Neolithic culture to Taiwan, the Philippines, and Indonesia thousands of years ago spoke Austronesian languages and were ancestral to the Austronesian speakers still inhabiting those islands today.

The other coincidence between archaeological and linguistic evidence concerns the cultural baggage that ancient Austronesians used. Archaeology provides us with direct evidence of culture in the form of pottery, pig and fish bones, and so on. One might initially wonder how a linguist, studying only modern languages whose unwritten ancestral forms remain unknown, could ever figure out whether Austronesians living on Taiwan 6,000 years ago had pigs. The solution is to reconstruct the vocabularies of vanished ancient languages (so-called protolanguages) by comparing vocabularies of modern languages derived from them.

For instance, the words meaning "sheep" in many languages of the Indo-European language family, distributed from Ireland to India, are quite similar: "avis," "avis," "ovis," "oveja," "ovtsa," "owis," and "oi" in Lithuanian, Sanskrit, Latin, Spanish, Russian, Greek, and Irish, respectively. (The English "sheep" is obviously from a different root, but English retains the original root in the word "ewe.") Comparison of the sound s.h.i.+fts that the various modern Indo-European languages have undergone during their histories suggests that the original form was "owis" in the ancestral Indo-European language spoken around 6,000 years ago. That unwritten ancestral language is termed Proto-Indo-European.

Evidently, Proto-Indo-Europeans 6,000 years ago had sheep, in agreement with archaeological evidence. Nearly 2,000 other words of their vocabulary can similarly be reconstructed, including words for "goat," "horse," "wheel," "brother," and "eye." But no Proto-Indo-European word can be reconstructed for "gun," which uses different roots in different modern Indo-European languages: "gun" in English, "fusil" in French, "ruzhyo" in Russian, and so on. That shouldn't surprise us: people 6,000 years ago couldn't possibly have had a word for guns, which were invented only within the past 1,000 years. Since there was thus no inherited shared root meaning "gun," each Indo-European language had to invent or borrow its own word when guns were finally invented.

Proceeding in the same way, we can compare modern Taiwanese, Philippine, Indonesian, and Polynesian languages to reconstruct a Proto-Austronesian language spoken in the distant past. To no one's surprise, that reconstructed Proto-Austronesian language had words with meanings such as "two," "bird," "ear," and "head louse": of course, Proto-Austronesians could count to 2, knew of birds, and had ears and lice. More interestingly, the reconstructed language had words for "pig," "dog," and "rice," which must therefore have been part of Proto-Austronesian culture. The reconstructed language is full of words indicating a maritime economy, such as "outrigger canoe," "sail," "giant clam," "octopus," "fish trap," and "sea turtle." This linguistic evidence regarding the culture of Proto-Austronesians, wherever and whenever they lived, agrees well with the archaeological evidence regarding the pottery-making, sea-oriented, food-producing people living on Taiwan around 6,000 years ago.

The same procedure can be applied to reconstruct Proto-Malayo-Polynesian, the ancestral language spoken by Austronesians after after emigrating from Taiwan. Proto-Malayo-Polynesian contains words for many tropical crops like taro, breadfruit, bananas, yams, and coconuts, for which no word can be reconstructed in Proto-Austronesian. Thus, the linguistic evidence suggests that many tropical crops were added to the Austronesian repertoire after the emigration from Taiwan. This conclusion agrees with archaeological evidence: as colonizing farmers spread southward from Taiwan (lying about 23 degrees north of the equator) toward the equatorial tropics, they came to depend increasingly on tropical root and tree crops, which they proceeded to carry with them out into the tropical Pacific. emigrating from Taiwan.

How could those Austronesian-speaking farmers from South China via Taiwan replace the original hunter-gatherer population of the Philippines and western Indonesia so completely that little genetic and no linguistic evidence of that original population survived? The reasons resemble the reasons why Europeans replaced or exterminated Native Australians within the last two centuries, and why South Chinese replaced the original tropical Southeast Asians earlier: the farmers' much denser populations, superior tools and weapons, more developed watercraft and maritime skills, and epidemic diseases to which the farmers but not the hunter-gatherers had some resistance. On the Asian mainland Austronesian-spea
