That's ridiculous. I am not basing the argument on modern social norms. I am basing the argument on universal human behavior. You can go talk to the most 'primitive' humans on earth if you want proof.

The most primitive people now alive are "modern" and display "modern" social norms. Yet truly modern people as you describe them interbreed like rabbits. Ever wonder why jews come in so many different colors?

Without the barriers of geography, people have always shown a proclivity to interbreed. That doesn't mean that humans and neanderthals did, it just means that your argument doesn't hold water.

That is a lie. The most primitive people now alive are virtually indistinguishable from the contemporaries of the Neanderthals.

Without the barriers of geography, people have always shown a proclivity to interbreed.

There are distinct patterns to the way that people interbreed and the circumstances within which they interbreed and none of them are even remotely comparable to those of humans that would've been contemporaries of Neanderthals.

This almost made me swear. LOL! Well, I did swear to myself.. :)

The reason Jews come in so many different colors is because Jews were conquered by an urban civilization and then dispersed across an urban civilization.

There were no urban civilizations in the era of the Neanderthals.

And human intermixing (between tribes/clans) in pre-urban cultures is so rare and fleeting as to be all but nonexistent.
