[Aztlan] FIRST CRITIQUES OF THE NEW FIRST AMERICANS GENETIC STUDY

[michael ruggeri]

Listeros,

The first critiques of this week's research report that a single  
population of prehistoric Siberians crossed the Bering Strait into  
Alaska and subsequently fanned out to populate North and South  
America and showed some data hinting that the coastal route may have  
been the way this group traveled through the Americas have now  been  
stated.

This study is the largest genetic study ever done on First Americans  
drawing on DNA from 29 groups across Canada, Mexico, Central and  
South America and groups in Siberia.

Tom Dillehay congratulated the researchers for carrying out the  
largest genetic study ever done on the First Americans but points out  
that the study excludes US Native Americans and Eastern Brazilians.  
The authors of the report promise to address genetic findings there.

Kari Britt Schroeder at the University of California at Davis points  
out that the study can't rule out small genetic contributions from  
other groups.

Science News Online has the update here;

It is now the task of those who posit other groups from  elsewhere  
being among the First Americans to show data to try and prove their  
case. This is why the seemingly incomplete data on Kennewick Man  
needs to be completed or explained more clearly.
