Thanks. He's just repeating the good old linear progress crap from the Victorian Era, best summarized IMHO by fringe writer John Anthony West -- a linear progression from stupid cave men to smart old us with our hydrogen bombs and striped toothpaste.
There have been different toolkits defined by the similarity in technique, and the techniques have been reproduced by modern knappers (basically, scientists who do practical research, bangin' rocks together), but who made which one is entirely a matter of agenda/opinion. The name given to each toolkit was picked based on the modern placename nearest where each was found (in the Americas, the Clovis points were first dug up and IDed near Clovis, NM, for example).
The master race hypothesis known as the Replacement Theory has the gracile, ballet-dancer-like ancestors of us all prancing on point out of Africa perhaps 50K years ago, with total biological superiority (there's no way to dress it up) and they didn't have to actually go out and just mass-murder everyone and everything they found -- they just replaced them.
How?
Don't ask so many darned questions.
Also, they never built a boat.
Oh wait, they must have built some boats, because a few people crossed into Australia 20K years ago, taking all the boats in the world with them. No one thought of it again for 14K years. Then about 6000 years ago, someone built more boats. But they didn't venture out of sight of the shore until the 14th century AD.
Except in the Pacific, which covers half the world's surface -- a small ethnic group of uncertain origins started sailing across unmarked waters and settling every little island where permanent habitation is possible, by approximately 500 AD. And they never ever crossed the entire ocean to the Americas. No one ever ever did that until 1492.
Of course, the prehistoric tools left by someone on Flores Island -- a landmass known to have been an island throughout all the sealevel declines during glaciations -- about 800,000 years ago. They must have built boats just to get over there. Then they stayed, and they'd taken all the boats with them. So, between 800,000 years ago and 20,000 years ago, no one ever built a boat.The Neandertal Enigma"Frayer's own reading of the record reveals a number of overlooked traits that clearly and specifically link the Neandertals to the Cro-Magnons. One such trait is the shape of the opening of the nerve canal in the lower jaw, a spot where dentists often give a pain-blocking injection. In many Neandertal, the upper portion of the opening is covered by a broad bony ridge, a curious feature also carried by a significant number of Cro-Magnons. But none of the alleged 'ancestors of us all' fossils from Africa have it, and it is extremely rare in modern people outside Europe." [pp 126-127]
