IMO Neanderthals did not disappear, they are still here today and are called n-gger .
Our Ancestors did not mix because they NATURALLY KNEW BETTER !

Early man steered clear of Neanderthal romance
No evidence of interbreeding between primitive humans.

ay have looked too different to attract modern man.

If our early ancestors did breed with their Neanderthal cousins,
they didn't make a habit of it,
according
to t
he
largest-ever study of early human DNA.
Researchers compared the preserved remains of four Neanderthals and five early modern humans found throughout Western Europe.
DNA from the two sets of samples was distinct enough to rule out large amoun
ts of mixing between the two.
"We detected no evidence of interbreeding,"
says David Serre of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, who took part in the study.
But he adds that, because of the scarcity of well-preserved DNA, it is impossible to be certain that such trysts never took place.
Neanderthals vanished from Europe between 30,000 and 40,000 years ago,
roughly the time that truly modern man made his first appearance in the region.
Researchers have be
en divided over whether the two groups ever came face to face - and if they did, whether relations were hostile or harmonious.
Family ties
Serre and his colleagues set out to shed l
ight on
this quest
ion by examining sequences of mitochondrial DNA taken from fossils.
These sequences are passed virtually intact from mother to offspring - if Neanderthals and modern humans interbred,
the sequences would be expected to overlap between the two groups.
But the sequences were e
ntirely distinct, the researchers report in PLoS Biology1.
"It's an advance," says Chris Stringer, who studies early humans at Britain's Natural History Museum in London.
The finding supports the theory that our earliest European ancestors replaced Neanderthals,
rather than mixing to form a single group that eventually gave rise to the people of today, he says.
But it's not yet fully clear how this process unfolded:
did modern humans bully their slow-witt
ed neighbours to extinction,
or did the Neanderthals die out and leave us to inherit an empty landscape?
"I don't think DNA can answer this question," says Ser
re.
Although the two
groups seem to have been genetically separate, the fossil record is too patchy,
and dating methods too unreliable, to say whether this was because they never met,
or because they simply didn't consider each other an enticing proposition.
Given the small number of fossils studied, it's also possible that interbreeding did occur,
he ad
ds, but that we have not found the evidence yet.
In my view, the Neanderthals were just unlucky

Such a match-up would have been genetically feasible, says Stringer.
The two groups were closer in genetic terms than other primates that happily breed today, he says.
Physically, however, they were very distinct, he adds.
Perhaps the Neand
erthals' thickset build and furrowed brow were just too different for romance to blossom.
So what did happen to the Neanderthals?
Stringer points out that Europe
's climate
was very unstable at arou
nd the time of their demise.
This, combined with the arrival of a cunning new competitor in modern man, could have conspired to wipe them out.
"If the climate had been stable, perhaps the two could have overlapped for some time," Stringer speculates. "In my view, the Neanderthals were just unlucky."
