First humans in Northern North America: 11,500-year-old baby fossils show humans 'paused' as they spread across the globe

One was a 12-week-old baby and the other a stillborn 30-week fetus

Date of burials is shortly after the dispersal of people from Beringia

Suggests Native Americans ancestors migrated from Asia to Beringia

They spent up to 10,000 years in Beringia before moving rapidly into the Americas beginning at least 15,000 years ago

DNA analysis of two infants buried in Alaska has shed light on the movement of the first humans in North America.
It shows the infants – who had different mothers - were from the northernmost known kin of two lineages of Native Americans.

The 11,500-year-old skeletons are significant because the date of the burials is a few thousand years after the first dispersal of people from Beringia into the Americas.

By showing that both genetic lineages lived so far north so long ago, the study supports something known as the 'Beringian standstill model.'

The model suggests that Native Americans descended from people who migrated from Asia to Beringia.
