[00:11.978]The ancestors of these Solomon Islanders [00:14.924]made that initial 60-mile crossing some 30,000 years ago. [00:31.165]Whether their ancestors paddled across in hollowed-out tree trunks like these, [00:35.530]or floated on giant bamboo rafts, no one knows. [00:55.602]And with land occasionally in sight, [00:58.723]they would have surely been tempted to investigate. [01:14.202]By the time people arrived, [01:15.980]the Solomons were packed with almost a quarter of the plants and animals found in New Guinea [01:26.197]including their old adversary, the saltwater crocodile.
