jan 1, 10000 BC - 12000 years ago ~ Break of the Landbridge:
Over the next few thousands of years
following the first humans to visit the
Americas, these humans spread across
the North, Central, and Southern areas
of the landmass.
The glaciers presumably melted about
12,000 years ago, making these humans
unable to move across the continents
of Asia and North America. At that time,
they were forced to adapt in the Americas.
