24,000-year-old boy’s skeleton suggests first Americans came from Siberia

Graf helped extract DNA material from the boy’s upper arm and “the results surprised all of us quite a bit,” she explains.

“It shows he had close genetic ties to today’s Native Americans and some western Eurasians, specifically some groups living in central Asia, South Asia, and Europe.

Also, he shared close genetic ties with other Ice-Age western Eurasians living in European Russia, Czech Republic and even Germany.

We think these Ice-Age people were quite mobile and capable of maintaining a far-reaching gene pool that extended from central Siberia all the way west to central Europe.”

Another significant result of the study is that the Mal’ta boy’s people were also ancestors of Native Americans, explaining why some early Native American skeletons such as Kennewick Man were interpreted to have some European traits.

“Our study proves that Native Americans ancestors migrated to the Americas from Siberia and not directly from Europe as some have recently suggested,” Graf explains.

The DNA work performed on the boy is the oldest complete genome of a human sequenced so far, the study shows.

Also found near the boy’s remains were flint tools, a beaded necklace and what appears to be pendant-like items, all apparently placed in the burial as grave goods.

The discovery raises new questions about the timing of human entry in Alaska and ultimately North America, a topic hotly debated in First Americans studies.
