Actually the "Clovis First" theory has a lot of credible challenges;
Were the Clovis people the first Americans?

PBS did a great special on this subject as well:

Most notably, the new dates suggest that Clovis might not have come first.

Archeologists have previously dated other sites from non-Clovis early Americans, from Canada to South America http://www.npr.org/templates/story/story.php?storyId=7565568

I agree. There have been too many holes poked in Clovis First for it to remain a viable theory.

Personally, I think the PalaeoIndians were a mixture of Asian, African and European invaders. I think a lot of eastern Native Americans had remarkably European like features and a lot of western Native Americans had strongely Asiatic Features. A numbner of South American indian groups appear to have African features.

The Clovis culture is the one at issue here ~ not an earlier one, nor a later one. Solutrean and Clovis technology appear to be so similar that you have to stand on your head to argue that they could possibly have different origins.
