America first populated in 'a single wave of migration from Siberia' no more than 23,000 years ago

 

 

Analysis of DNA of present day indigineous people throws new light on how our ancestors crossed the Bering land and ice bridge which then connected modern-day Chukotka and Alaska.

A study led by the Centre for GeoGenetics at the University of Copenhagen, asserts that there was one one initial migration from Siberia to America. 

 

Around 10,000 years later there was a split in these human ancestors into two groups, which anthropologists call  Amerindians (American Indians) and Athabascans (a native Alaskan people).

 

Previous research had suggested that Amerindian and Athabascan ancestors had crossed the strait independently.

 

'Our study presents the most comprehensive picture of the genetic prehistory of the Americas to date,' said Maanasa Raghavan, one of the study's lead authors.

 

'We show that all Native Americans, including the major sub-groups of Amerindians and Athabascans, descend from the same migration wave into the Americas.'

 

The timing is clearly off, bu the "single wave" proof is interesting.

The Bering Islands land bridge is only guesswork, too...

They all came from Babylonia/Sumeria. Don't these (un)intelligent people know anything?

My DNA connected me with Athabascan group. I think that wave hit central mid west America and split up in the 1300's because of famine. We will know more in the NW.
