Finished watching the vid, certainly interesting.
I used to be a big proponent of the solutrean hypothosis, and I recognized the real significance of the Clovis/solutrean spear technology, on my own
before my exposure to the solutrean hypothosis.
I realized that in tundra/polar conditions the bardst thing to find is a good straight piece of wood with which to make a spear. And the method both
cultures use to fix a point to the shaft with a fore shaft in a harpoon like tool, exemplifying the importance of the shaft over the point.
You can carry around a bag of points, but you might only have one or two shafts to work with.
It's clear now that the human presence in the Americas predates the solutrean presence in Europe.
With the newest work in genetics showing a radically different model of human dispersal than it did when this conference was, ie,
Neanderthal/denisovan/ human split 1,000,000 years ago,physically modern humans showing up 300k years ago/ the native American divergence at 175k
years ago, the old solutrean model has to be re examined. There is also the fact that native Americans are more closely related to hsn and hsd, than
either Europeans, for hsn, or southe east Asians for hsd.
Another interesting facet of this conversation is that the oldest dog found, from the altai mtns, more closely esembles, both genetically and
physically, ancient native American dogs than it does Eurasian and European dogs.
When you also look at the dention of modern humans there is a definate east to west trend in despecialization
in human dention. Native Americans show a high degree of shoveling of the incisors, a trait that goes all the way back to homo erectus. Shoveling
rates decrease as you move west among population in Eurasia culminating in the very generalized teeth if European populations.
The oldest native American remains have one thing in common that are characterized as being "archaic" in morphology, and not like those of Asia,
with a few exeptions, and the eauropeans at the same time are characterized as archaic.
Some of the earliest remains were so archaic that it was postulated they were related to Asian homo erectus.
I have know come to believe in a very early entrance into the new world with back migrations into Eurasia, and that the solutran connection was two
way, the pre clvis people who worked the sea ice margins ran into the solutrean people and they traded goods .
