Fascinating.
Sounds like a case of willful, active ignorance to me.
Isn't there a major problem w/ the climate around Zeiten in that he was able to pass off the skulls of modern man as Neanderthal? I'm not an expert & I probably wouldn't know the difference, but I would think that other anthropologists should have raised some questions long ago. At least in the one case, the skull was intact--that is, not just a couple of little pieces of bone.
