Well, I'm skeptical. The main or only evidence for the hypothesis is a similarity in methods of making stone tools. But presumably there are only so many ways to make a stone spearhead.
There is a major shift about to take place in the whole argument. Some papers are in the works that I think will show that Clovis was indeed first--but not as now envisioned.
Ooh, I love surprises.
And it would particularly tickle me if the reinterpretation of the Clovis people was based on a reinterpretation of the Clovis site.
