No mention of the recent genetic studies that show genetic similarity between deep-Amazon Native Americans and indigenous Australo-Melanesian people, which would seem to support this hypothesis[1]. It seems like there were at least two (actually probably 4) waves of non-European colonization of the Americas - the "Kelp Highway" one described here, followed by the big-game hunters who eventually wiped out that initial wave almost everywhere except in the marginal lands deep in the Amazon jungle. There was also the Athabaskan / Dené and the Eskimo after that. 13,000-15,000 years ago: Kelp Highway settlers 11,000-13,000 years ago: Big-game hunting ancestors of majority of Native Americans (Clovis culture) at time of European contact arrive and mostly wipe out the first wave of settlers except in isolated areas like the Amazon jungle [somewhere in between]: Athabaskan / Dené come across from Siberia and occupy Alaskan / Canadian interior, as well as parts of the Pacific Northwest and American Southwest (not sure how they got there) ~3,000 years ago: Inuit / Inupiat / Yupik migration and settling of the circum-polar region [1] http://www.nature.com/nature/journal/v525/n7567/full/nature14895.html http://www.nature.com/nature/journal/v525/n7567/full/nature1...
