[Aztlan] THE BERINGIAN POPULATION AND THE FIRST AMERICANS

[michael ruggeri]

Listeros,

This is an update of an article I sent on December 1, 2000. According  
to DNA studies carried out by the University of Florida Genetics  
Institute scientists of New World DNA, people from Asia moved into  
Beringia, the land mass that appeared connecting Siberia to Alaska  
when sea levels fell, but were blocked from entering the new World by  
two large glaciers. People lived for 20,000 years in Beringia until  
about 15,000 years ago when the glaciers melted and people could move  
from Beringia to the new World. Mutations and genetic patterns began  
to accumulate in the Beringia population during those 20,000 years  
that show up in most New World indigenous populations today. In the  
earlier article, it was revealed that the geneticists sampled DNA  
from thousands of present day indigenous people in 29 groups across  
Canada, Mexico, Central and South America to arrive at their  
conclusions. In the earlier article, it was mentioned that the study  
excludes Native Americans and Eastern Brazilians. The authors of the  
report promise to address genetic findings there later.

The theories of an arrival by people following a coastal route up to  
40,000 years ago now have the challenge of finding countervailing DNA  
evidence to prove their case or compelling archaeological evidence  
that would prove the earlier arrival.
