Four species of Neanderthal, three of them that looked like modern humans, not Mousterians
When we say a male or female is good looking, we mean they look like Neanderthals. When we say somebody is butt-ugly bufferilla hideous, we mean they look like Cro Magnons. People don't know that is what they mean but nevertheless that is what they are really saying. The three species of Neanderthal had wide socket receding eyes and highly symmetrical skulls, far more so than Homo Sapiens has ever had.
If you see somebody who even appears to pass some test of bisymmetry in the face, that is always Neanderthal gene expression.
If the Denisovans were around 400,000 years ago living alongside the other three breeds, this simply expands on a mystery that is already demolishing the orthodoxy.
