Yes, of course the Yamato and the Maya must have come from Siberia, of course the whole so-called Clovis hunters has been called into question as bad science (http://www.bbc.co.uk/news/science-environment-15391388) Old American theory is 'speared' By Jonathan Amos. And even if weren't the idea that anything in human culture remains static, frozen in time and yet without a shred of cultural evidence to back it up outside of "could've/ would've/ should've" is what we call bad science. Find me an article in the NPR, BBC or Science magazine showing any evidence that these two people have any cultural links whatsoever and then I'll agree it belongs in this article. Anything else is a waste of our time and energy.
