"The ancient remains of a teenage girl discovered deep underground in Mexico are providing additional insights on how the Americas came to be populated."

"Samples taken from a tooth were used to both date the remains and test for DNA"

"Aged 15 or 16 at death, the girl lived at least 12,000 years ago. Researchers have told Science Magazine her DNA backs the idea that the first Americans and modern Native American Indians share a common ancestry."

Lab analysis of teeth and bone samples link her to a particular genetic lineage known as Haplogroup D1.
Interesting, they went from asia to america very early

Aren't Amerindians though hybrids between mongoloids and ancestral north eurasian populations

Lab analysis of teeth and bone samples link her to a particular genetic lineage known as Haplogroup D1.
So far, they have only tested mtDNA. "Dr Chatters confirmed that unravelling Naia's nuclear genome was a future priority."

Reconstruction

The new facial reconstruction likewise does not support an Asian relationship, as, according to the scientists who have examined Naia, “her skull has a shape associated with African or South Pacific populations rather than the typical Siberian look.”
