... no such link between Neanderthal DNA and modern European DNA could be established ...
There goes my theory about the origins of the French.
The dimensions and bone-mass of neanderthal specimens suggests that sex with same, male or female, would have left the human participant injured or dead. Most likely dead. Or wishing that he was, or she was, or whatever. E.g. imagine a human female attempting to give birth to a half-neanderthal child--YIKES! And a neanderthal female would probably just laugh at a sexually excited human male (ahem).
Neaderthals were optimized for heavy lifting etc.

There is a local fellow near me who runs a junkyard that they have obviously overlooked.
