It appears that if Calico and Lugoa Santa
are to be believed
and they appear very good,
that there was a process of both evolution and migration
and that men of an early type with pronounced brow ridges ( bone heads)
were here before Clovis.
Clovis tools / blades might actually be an indigenous type of tool
invented by an evolving American modern human ( have nothing really to
do with a Siberian bridge).
What seems clear is that American prehistory anthropology hasn't been
very much of what the rest of the world would call science for more than
50 years. Such behavior as the record shows would be a source of deep
shame in any other science.
Waves of modern humans from probably both Europe and Asia did come, but
probably in boats and dog sleds following their prey animals ( seal and
Walrus and caribou).
Anyone saying the current history text doctrine being taught of Clovis
first and a Siberian bridge should probably have a drum roll as they
leave ... ( in any other science they might be killed by rioting
undergrads!). Lies, suppression and academic bullying really have no
place in a decent science.

The most compelling models concerning the peopling of the
Americas consider that modern Amerindians share a common
biological pattern, showing affinities with populations of the
Both analyses indicated that morphologic variation in
Southern Amerindians is extremely high: an FST of 0.01531 was
obtained for Southern Amerindians, and values from 0.0371-
0.1205 for other world regions. Some aspects linked to the
time and mode of the peopling of the Americas and various
microevolutionary processes undergone by Amerindians are
discussed. Some of the alternatives proposed to explain this
high variation include: a greater antiquity of the peopling
than what is mostly accepted, a peopling by several highly
differentiated waves, an important effect of genetic drift,
and gene flow with Paleoamericans.
