Some Final Generalizations

Perhaps I may finally sketch, in brief, some of the major transformations which I believe prehistoric Austronesian societies underwent in Island Southeast Asia between about 4000 BC and AD 1.

  1. 4000-3500 BC; Initial Austronesian expansion to Taiwan; settled cereal and tuber agriculture, limited seafaring.
  2. 3000 BC; Proto-Austronesian expansion to the northern Philippines; improvement of seafaring technology, stylistic shift from cord-marked to plain or red-slipped pottery.
  3. Late third and second millennia BC; Proto-Malayo-Polynesian dispersal from the southern Philippines to Borneo, Sulawesi and the Moluccas; equatorial enhancement of fruit and tuber production vis-à -vis cereals, except in more southerly and climatically-seasonal islands such as Java where rice has presumably always maintained its pre-eminence. One development of great interest which might have occurred about this time might have been the beginnings of forager adaptations to the rainforests of Borneo and Sumatra (see Sather, this volume).
  4. Second/first millennia BC? Beginnings of mobile maritime (proto-sea nomad?) adaptations around the Sulu and Sulawesi Seas (cf. Bellwood 1989 for a maritime economy with long-distance exchange at Bukit Tengkorak, Sabah, around 1000 BC), and possibly elsewhere. These, in turn, might have laid some of the seafaring groundwork for:
  5. Middle and late second millennium BC; Lapita colonization of Remote Oceania to as far as Tonga and Samoa. Seafaring skills were here developed further amidst an ever-expanding vista of uninhabited islands, but with few opportunities to settle on large western Melanesian islands (especially New Guinea) already inhabited by Papuan-speaking peoples.
  6. Second/first millennia BC? Austronesian settlement in Vietnam and Malaya, in both regions in competition with pre-existing agriculturalists.
  7. 500 BC and after. Introduction of bronze and iron metallurgy into Island Southeast Asia. Dong Son drums were also traded from Vietnam into the Sunda islands, extending from Sumatra to the southern Moluccas.

Perhaps the metallurgical introductions listed last above were no more than side effects of something much greater; the incorporation of parts of Island Southeast Asia into a network of Old World trade stretching from the Mediterranean to eastern Indonesia. Indian pottery of c.200 BC to AD 200 has now been unearthed in Java and Bali (Ardika and Bellwood 1991), and at the same time the archaeological record reveals a hitherto-unprecedented level of similarity in local pottery design and manufacture across a huge region which includes coastal regions of the Sunda islands, Borneo, Sulawesi and the Philippines. It is possible that a great deal of linguistic assimilation of prior diversity occurred from this time onwards, for instance by the Malayic languages (especially Old Malay itself), Javanese and perhaps other languages or subgroups (cf. Blust 1991 for the possibility of some kind of linguistic levelling in the Philippines). By AD 500 the Western Austronesian area was perhaps a zone of continuously-flourishing inter-island travel and trade, with the odd proviso that Taiwan, where so many crucial developments had once occurred, was now divorced into an almost total isolation from the rest of Island Southeast Asia (Meacham 1984-5). Such are the enigmas of history.
