Americas. The prominent idea has been that a sort of land bridge
formed during the last ice age and people migrated from Asia.
But people may not have just waltzed over the land bridge and
spread across the Americas. Instead, they may have settled in
northern Alaska for a while first.

Scientists have sequenced the mitochondrial DNA from two infants
found buried together at an Alaskan campsite some 11,500 years
ago in a paper published Monday in the journal Proceedings of the
National Academy of Sciences. http://www.csmonitor.com/Science/2015/1027/What-do-ancient-babies-reveal-about-travel-by-ice-age-Americans
