11.5 kya DNA supports Beringian Standstill hypothesis

Scientist have long debated how humans originally arrived in the 
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. 

And the newest clues come from a surprising place: babies. 

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.
