I think the biggest set of fallacious claims made are made on the "Clovis Point" finds. The author makes broad sweeping statements based on these small finds that are not really supported by the evidence, nor do any of the experts in the field agree. Additionally, the author goes to great lengths to make the claim that the earliest societies were egalitarian "commune" societies of hunter gatherers, by cherry picking very specific finds, and completely ignoring any counter-examples. He also draws broad conclusions on very weak evidence. For example, he looks at the ruins of certain ancient sites only partially excavated, notes that there's no evidence of a "central large building" and draws the conclusion that these societies had no central gov't or singular leadership. These are wildly fallacious arguments. It's the sort of thing we see when someone who is very politically active does direct historical research. It's too easy to biased your research if you're specifically looking for evidence to support your modern politics.
