Dar,
The occurence of bones,which have been modified by humans,suggests that
there were people in the Crow River basin well before the last glacial
maximum [J Cinq Mar,2001].Whether the group was large enough to survive
and colonize the south is a moat point.The earliest migrants to North
America may not have been [?] sufficiently numerous to exist in a new
environment.Have you seen any articles,which discuss the size of
effective migrant colonists?
