"However the "experts" say that the Neanderthal DNA is incompatible with homo sapien."

There is human DNA found in Australia that is incompatible with modern human DNA. I think it came from Mungo Man.

There is human DNA found in Australia that is incompatible with modern human DNA. I think it came from Mungo Man.

Mungo Man's DNA suggest he might be an erectus/homo sapien. This wouldn't be a problem for the Creationists because, as I understand them, they consider erectus, Neanderthal and homo sapien as just human variations.
