It is supposed that Paleolithic Man migrations
from Northern Asia via Beringia to Northern America happened past 12 thousand
years ago. This supposition is based on opinion that ancient presence of Man in
Eastern Siberia is dated 18 thousand years. This data is no longer current. Now
it is known that Paleolithic Man came to Siberia c. 900 thousand years ago and
since he has not deserted Siberia. It allows to suppose that the earliest
migrations of Paleolithic Man via Beringia to the New World could take place by
“nomadic scouts” c. 260-250 thousand years ago. Traces of this migration were
found in the upper stream of Angara-River, in the middle stream of Lena-River
and on Chukotka. Migrants could make use of the exposed shelf in Beringia
during the end of Maximum Ice. Ancient migration c. 31-30 thousand years ago is
dated more confidently. The reasons and
mechanisms of these migrations are discussed. During that time the central
parts of the Beringia shelf was drained. During the time of maximal regression
of sea level at the maximum of the last glaciation Paleolithic Man migrations
from Northern Asia to Northern America are improbable, because in that time
Northern America was covered by continuous Lavrentide-Cordilleran Ice Sheet and
only one part of North Alaska remained free from glaciers.
