Clovis having been the first bifacial point here is just wrong. That aside though, it's striking (when you encounter something like this) to realise how much our thinking tends to revolve around what we do know (or assume we do), and the extent to which some basic considerations (like these) that should be obvious are in some kind of mental blind spot. We "see" what promises gratification (understanding) and don't see what's un-promising of it, even though it's arguably of equal or greater significance in the picture overall.
Not that this is going to change anyone's mind, but it's the same story writ large in the neverending conjecture centering on monkeys "becoming human" through trial and error. It's such an attractive notion that basic principles (freely acknowledged in other contexts) calling it into serious question are cast to the wind.
One such would be the noteworthy absence of the crocoduck (and "missing links" in general) from the fossil record, forcing the grudging admission that, while circumstances
can elicit adaptions up to an extent, new species appear suddenly. And do so with monotonous regularity.
Why humans should be the stellar exception to this is never explained. Possibly, because acknowledging it would open yet a bigger can of worms (?) But damage control isn't science, IMHO.
Credo quia absurdum isn't only operative in the field of formal religion. If you want man to have evolved from apes with sufficient intensity, well, then, he did.
