Hi Kronckew,
I'm still not sure about the Clovis point connection. The problem there is that points with similar designs show up on opposite sides of the globe, with nothing in between, and different designs before and after. To me, that suggests that the craftsmen making them solved similar problems (i.e. mega-game hunting) the same way, rather than that the design was invented once and diffused out.
Using the same logic, I could point out that, in more modern times, Sardinian and Hmong kitchen knives are largely identical (and both look a little like a flyssa and a talibon, oddly
). *Obviously* this means that Hmong and Sardinians trade with each other. It could be that they didn't have a lot of money, and independently came up with the same do-it-all knife design so that they could do all their chores with a single knife.
Best,
F
