"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.
