I do not take kindly to people insulting Chelsea Clinton.

Why would you assume cross-breeding is possible?
Why would you assume it isn't?

The lack of DNA is a very big hint.



They haven't been by my house to test DNA yet, therefore they haven't
tested all the DNA.

If they did the same test from the same demographic samples 2000 years
ago, would there have been no trace?

How about 5000?

10,000?

20,000?

Surely many races have gone extinct in the last 30,000 years. Some of
them may have had some neanderthal DNA in them.




The only reason for the invention of interbreeding was by people who did not
like the idea of extermination. It was not for any other reason. There was never
a question that Neanderthal was different from archaic/Heidelberg among
anthropologists. The only disagreement was based upon explaining the
disappearance. That they disappeared with the ice age should be a very big hint.

Something about them related to their breeding cycle not their life style was
dependent upon the ice age. Damned if I know what it was. If they were not
always on breeders like us it could have been anything.

Oh, that's right, there's that retard notion that archaic moderns
& neanderthals were "different species" in the same way that
modern humans & sheep are "different species."

As for different species the skeletal remains are a greater difference from
modern humans than between humans today. There are clearly climatic adaptations
which our kind of humans never got near even under natural selection rules so
there was a different starting point for each. So maybe their cold adaptations
were a detriment when the climate got warmed. The bigger nose cavity to warm air
may have been more susceptible to airborne diseases. And such diseases would be
more common as it got warmer on average.

You'll have to explain that one.

The names indicate different species.

In addition we have archaic/Heidelberg skulls and Neanderthal skulls. You have
to break all the rules of cross-breeding to have a modern skull arise from that
mixture.

And if you accept us type humans arising 100,000 years ago and running into
Neanderthal about 60,000 years ago (but maybe as little as 40,000) then you have
a great problem with a hybrid becoming established and repopulating Africa AND
Asia and the New World so quickly. If you do not have all that then you have the
European version of us being the only hybrids. That is not indicated in any
evidence found so far. Europeans are closer to the rest of the world in every
physical aspect than to Neanderthals.

Are there any other questions?

Do you have any credible evidence to the contrary of what I said?
