In England interspecies breeding happens all the time ~ they've even stopped trains to watch.

But, that's a different issue. There's NO REASON to think of the Neanderthal as a different species ~ more like a different "race" I am sure.

One hypothesis about how they survived the Northern climate during SEVERAL ice ages is that they had twins in every pregnancy. That kicked their reproductive rate up to match the need.

That probably gave them four active mammaries.

Again, we digress. I'm still POd at the dentist for busting through that bony plate the first time I had Novocaine. It hurt.

"That probably gave them four active mammaries."

Now there's an argument against 'natural selection'...
