A Simon Fraser University archaeologist and his colleagues at the University of Queensland in Australia have significantly narrowed down the time frame during which the last major chapter in human colonization, the Polynesian triangle, occurred.
SFU professor David Burley, Marshall Weisler and Jian-Xin Zhao argue the first boats arrived between 880 and 896 BC. The 16-year window is far smaller than the previous radiocarbon-dated estimate of 178 years between 2,789 and 2,947 years ago.
