What are the similarities between the neanderthal and human?
Both interbred and became one species.
Modern human and neanderthal are similar by having smaller eyebrow ridges, very narrow holes where the nostrils join the skull, and a shin bone that is flat on one side and concave on the other. Another similarity is that they have a large bulge at the back of the skull, a prominent projection around the elbow joint, and a narrow socket at the shoulder joint.
Why are the neanderthals dying out?
They were less well-adapted to the climate changes that occurred across Europe at that time. Others cite evidence of a more brutal end, in which Neanderthals were slaughtered by modern humans.
According to the researchers, the populations probably blended together through sexual reproduction. One said, "Extinction through absorption is a common phenomenon."
