the retreating ocean
exposes a great land bridge
:02:05
a thousand miles wide
connecting Asia to America.
:02:17
Across this corridor, a river
of living creatures would flow.
:02:23
It was the genesis

:02:25
that would inhabit the Americas,
and this was it's Eden.

and sheltering valleys

of all predators.

in small bands from Siberia
:03:46
pressing east in pursuit of game
:03:49
unaware they're discovering
a continent.

The hunters are sustained
by bison, moose, woolly mammoth
