It's 40,000 years ago, actually

As far as mitochondrial data shows, they first arrived on Alaska as one group
They split up.
The first one move forward and became the native americas. Everyone - from aztecs to incans to Olmecs - all came from 24 mothers

Meanwhile: the second group got stuck by a winter that lasted for 10000 years which caused their body to adapt to the cold too much and found the heat of the south too uncomfortable for them.
They became the Eskimos

Cool stuff to learn about
