Neanderthals.

How we have had to listen to non-stop guesswork over many decades about the 'apeman scenario' of so-called Neanderthals by evolutionary scientists.
We now find that they were fully integrated with other humans. Surely - nothing more than differing racial characteristics separated them.
One more scam which found its way into school textbooks as 'fact'.
