[Aztlan] Important genetic find on the First Americans

[michael ruggeri]

Listeros,

New genetic evidence published in Current Biology points to two  
separate groups arriving in America simultaneously. One group entered  
from Beringia 15,000 to 17,000 years ago along the ice-free Pacific  
coastline. Another traversed through an open land corridor to arrive  
east of the Rocky Mountains. Almost all Native Americans all the way  
to South America descend from these two groups.

Italian geneticists have found that the haplogroup D4h3 spread along  
the Pacific Coast all the way to Tierra del Fuego. The other  
haplogroup, X2a, spread through the ice-free corridor and remained  
restricted to North America.
