Here's a better selection of Neanderthal skulls:

A rather large variety of skulls seem to be classified as Neanderthal. I can see a lot of obvious differences between a lot of them that make me wonder what features they have in common such that they're all classified as Neanderthal.
What is intriguing to me about the alleged hybrid skull is the distinctly un-homo sapiens sapiens brow and sloped-back forhead. This is consistent with the notion of a human/homonid hybrid.
What that means, at the very least, is that his guy somehow got hold of a properly configured skull with which to perpetrate a hoax. Let's not forget Piltdown Man. The guy is also Russian, and Russian science is traditionally riddled with pseudo-science.
It would be nice to get this skull to the US and have it tested and examined by forensic pathologists and forensic anthropologists.
Bourtsev's site also says that some of the grandchildren are still alive. It would be nice to be able to fly some of them to the US and have them thoroughly examined: DNA and MRI's, and whatever else might reveal anything of interest.
