Analysis of information sources in references of the Wikipedia article "Indigenous peoples of Mexico" in English language version.
AROUND 36,000 years ago, a small group of people living in East Asia began to break off from the larger ancestral populations in the region. By about 25,000 years ago, the smaller group in East Asia itself split into two. One gave rise to a group referred to by geneticists as the ancient Paleo-Siberians, who stayed in Northeast Asia. The other became ancestral to Indigenous peoples in the Americas.
