No evidence for widespread island extinctions after Pleistocene hominin arrival

We provide global assessment of the possible link between Pleistocene hominin arrival and island extinction. The existing records on islands around the world do not support a significant and detrimental impact on island biotas following island colonization prior to the Holocene. This suggests that models using island extinctions as evidence in support of anthropogenic megafaunal overhunting, or as extensions of continental-level extinctions, need to be reconsidered.

"Superhighways" of the Original Australians Uncovered by Virtual Migrant


While there has been general consensus about the approximate date of arrival of these ancient migrants, scientists knew little about the paths that the newcomers to Sahul traveled, as they moved across the continent and established their settlements or carved out niches as hunter-gatherers so long ago. Archaeological sites linked to these distant times are difficult to find, and what has been discovered so far has not been sufficient to provide definitive answers about overland travel routes.
“We decided it would be really interesting to look at this question of human migration because the ways that we conceptualize a landscape should be relatively steady for a hiker in the 21st century and a person who was way-finding into a new region 70,000 years ago,” said study leader Stefani Crabtree, an archaeologist and computational social scientist affiliated with a New Mexico-based scientific think tank known as the Santa Fe Institute. “If it’s a new landscape and we don’ ....
