Why do so many think the north Asians sent out
a bunch of RSVP letters ... "We are now going to
go to the new continent, say if you plan join us !" ?
Conditions/means to cross from north Asia to north
America surely lined up for long and many periods.
In short, people didn't show up in NA all at once,
they dribbled in starting maybe as far back as
50,000+ years.
Not MUCH evidence dating back into that range for
obvious reasons, but there is SOME.
As best I've been able to find, there was a group
in north Asia that for some reasons (ice?) decided
to get the hell out of Dodge. Some went west, the
Saami may be partial derivatives, while others
fled west. Likely a few Chinese involved maybe
even a few Denisovans in the mix, but mostly this
north Siberian group.
Genetic analysis will continue to help pin down
the population particulars. However for good
dating, we need more durable relics.
I would NOT be surprised if humans made it to
NA even 100,000+ years ago and set up little
colonies. Every new group would interbreed with
the old.
