Could be. I carry a chunk of DNA from a 45,000 year old femur dug up by some dirty piece of ice in the middle of Nowhere, Siberia, and it is shared with the Na-Dene genome in North America. :^)
Wow, that’s cool. Were you able to trace your family line back to that cave man? Siberia? Guess you don’t much care for Stalin or Putin.
Are you of European descent? I believe that relatives of that 45,000 year old specimen went both east to Siberia and the New World, and west to Europe!
