"Our results use cutting-edge computational methods derived from evolutionary biology on a large database of language data," says Dr Alexei Drummond of the Department of Computer Science. "By combining biological methods and linguistic data we are able to investigate big-picture questions about human origins".The Science Daily site also provides links to several other articles in a similar vein.
The results, published in the latest issue of the journal Science, show how the settlement of the Pacific proceeded in a series of expansion pulses and settlement pauses. The Austronesians arose in Taiwan around 5,200 years ago. Before entering the Philippines, they paused for around a thousand years, and then spread rapidly across the 7,000km from the Philippines to Polynesia in less than one thousand years. After settling Fiji, Samoa and Tonga, the Austronesians paused again for another thousand years, before finally spreading further into Polynesia eventually reaching as far as New Zealand, Hawaii and Easter Island.

Wow. So it turns out that Polynesia has also been an integral part of China since ancient times. Who would have guessed?
ReplyDeleteIt's a very interesting finding, for Taiwan, especially.
ReplyDeleteas "cradles of civilisation" go, your preamble left out the great rift valley, sir..., nonetheless, thought provoking stuff. I'm off to watch old episodes of The Wire and put off my inevitable trouncing at Scrabble.

DNA is the definitive method to study human origins. Language study is fascinating but not precise.
ReplyDeleteThe same issue of Science (January 23, 2009) published two independent studies about Pacific islanders migration. One used computer/linguistic approach and the other used molecular technique of genotyping Helicobacter pylori (the ulcer-causing bacteria) obtained from guts of local residents. Both studies reached essentially the same conclusion. Curiously, the Science Daily article cited the linguistic study but not the molecular one (the more intriguing approach, in my opinion).
ReplyDeleteIt is rather clear that those ancient "Taiwanese" (at around the time, some of pyramids were being built) must possess phenomenal navigational skills otherwise the consequence will not be hard to imagine.
Anon: The DNA evidence says pretty much the same thing. Also, this study was really innovative and groundbreaking--it made Science, which unless you're an annual mention for the Nobel, often becomes news in itself.
