If it were a different hominid then where are the skeletal remains from them? It is illogical to dismiss homosapiens for lack of evidence and suggest a different species with no evidence.
we dont have a single skeletal remain from before 13,200 years ago in the americas homo sapien or otherwise. it is much more common to find evidence of humans instead of the actual remains. See the posted article where they use broken mammoth bones as evidence of human presence.
Evidence of the clovis people is mostly the result of the iconic spear tips.
if humans were around for 37 thousand years and these people were the direct Ancestors of modern American Indians they would have had sufficient IQ to be using sophisticated tools and those tools would be in the fossil record.
We have more advanced technology than cavemen yet no real evidence that we are smarter. Tools are a technology, and technology spreads. It is not intrinsically linked to an IQ. Cultures evolve faster than species. So using that as a basis of speciation is silly.
"yet no real evidence that we are smarter"
This is exactly what I am getting at. There is no real evidence that people living 25 thousand years ago were any dumber than people who live today. Over the course of 10 thousand years they would have developed tools even living in isolation. Tools made of wood or fibre wouldnt last long but bone and stone tools would.
Either they had such a small population that they dwindled and died out (meaning they were not around for the entire time period leading up to the introduction of the clovis) or they were not true humans
If they were thriving when the clovis arrived we would have lots of evidence of their existence. We know exactly when homo sapiens arrived in regions of europe because archeologists have found loads of crushed neanderthal skulls from the genocided populations of previous non homosapien inhabitants.
