For John, BLUF: I don't think this is a surprise, but it is interesting confirmation—Native Americans didn't spring up here, but migrated across what is now the Bering Strait. Nothing to see here; just move along.

Here is the lede plus one:
Using genomic analysis, scientists have traced the oldest link between the earliest Native American populations and the people of Siberia's Lake Baikal region.Interesting.Modern humans have populated the lands surrounding Lake Baikal since the Upper Paleolithic. Previous studies of the region's population dynamics suggest the transition from the Neolithic to the Bronze Age was marked by genetic turnovers and admixture events, but the timing of the human migrations and cultural interactions that characterized this place and time in human history aren't well understood.
New genomic analysis of ancient remains in Siberia -- detailed this week in the journal Cell -- have offered scientists fresh insights into the movements of human populations across Eurasia and into the Americas at the end of the Stone Age.
"Previous studies observed the genetic differences between individuals from different time periods, but didn't investigate the differences by dating the admixture events," lead study author He Yu, postdoctoral researcher at the Max Planck Institute for the Science of Human History in Germany, told UPI in an email. "Our study reports a 14,000-year-old individual, which actually fills in a large blank of ancient genomes in this region, between 23,000 and approximately 8,000 years ago."
