I had no idea that this was the archeological consensus as when I was taking anthropology classes it was widely agreed upon that the closest genetic relative to Native American peoples were the southern Altai People of central asia.


I think it was just one hypothesis that was gaining some popularity. Not a consensus, but enough traction for these other folks to look into.


How popular was this theory? Never even heard of it. A Siberian population that split several ways one of which later became the Jomon -- maybe. Not people already living in Japan.


I've never heard of it either. Sounds like this theory should have been blown out of the water after the first genetic haplogroup studies happened.


It’s also generally accepted now that humans have been in North America considerably longer than 15,000 years - in September they published findings on fossilized footprints in New Mexico that are 23,000 years old, and other findings have suggested habitation for even longer.


Actually comparative genetic analysis firmly places the Amerindian migration into the Americas between 15,000 to 12,000 years ago. Those footprints are likely from a terminal population of humans unrelated to modern Amerindians.


Falsified or disproven, not "debunked". The latter has connotations of fraud.


A widely accepted theory of Native American origins coming from Japan has been attacked in a new scientific study, which shows that the genetics and skeletal biology “simply does not match-up”. The findings, published today in the peer-reviewed journal PaleoAmerica, are likely to have a major impact on how we understand Indigenous Americans’ arrival to the Western Hemisphere. Based on similarities in stone artifacts, many archaeologists currently believe that Indigenous Americans, or ‘First Peoples’, migrated to the Americas from Japan about 15,000 years ago. It is thought they moved along the northern rim of the Pacific Ocean, which included the Bering Land Bridge, until they reached the northwest coast of North America. From there the First Peoples fanned out across the interior parts of the continent and farther south, reaching the southern tip of South America within less than two thousand years. The theory is based, in part, on similarities in stone tools made by the ‘Jomon’ people (an early inhabitant of Japan, 15,000 years ago), and those found in some of the earliest known archaeological sites inhabited by ancient First Peoples. But this new study, out today in PaleoAmerica – the flagship journal of the Center for the Study of the First Americans at Texas A&M University – suggests otherwise. Carried out by one of the world’s foremost experts in the study of human teeth and a team of Ice-Age human genetics experts, the paper analysed the biology and genetic coding of teeth samples from multiple continents and looked directly at the Jomon people. “We found that the human biology simply doesn’t match up with the archaeological theory,” states lead author Professor Richard Scott, a recognized expert in the study of human teeth, who led a team of multidisciplinary researchers. https://www.tandfonline.com/doi/full/10.1080/20555563.2021.1940440


It was never widely accepted


I thought scientists believed the [Out of Eden](https://www.nationalgeographic.org/projects/out-of-eden-walk/#section-0) route as shown on the linked map by green arrows.


Wouldn't it be china? Like the land bridge connects to western Russia but I can easily see early Chinese migrants making the cross.
