This report
can be considered scientific housekeeping and assures us that we are certainly
dealing with interbreeding. I have no
doubt, but only because I am familiar enough with natural and almost barbarian
societies to have read plenty of clear evidence. We only need to recall the Altai wild women
who became a convenient source of sexual release within a small group. This led to several offspring.
Quite clearly, interbreeding becomes inevitable in anything approaching primitive conditions. Lack of opportunity is not a viable argument at all when we have historical evidence in the form of a direct Human Altai hybrid. A serious genetic separation was needed and considering the present thinking that we just happen to be initially a boar female primate hybrid that worked out and back breed into the mother’s tribe, this problem is small potatoes.
At least we
have eliminated the failed theory of outright extinction and finally understood
that we are dealing with a failed life way that limited populations. In that circumstance the small population is
naturally absorbed and back bred into the larger population. The only way to avoid simply disappearing
from the visible world is to use the Jewish protocol.
It goes
without saying that the Neanderthal genome is absorbed into our Eurasian
genome.
New
method confirms Humans and Neandertals interbred
Posted by TANN
Technical objections to the idea that
Neandertals interbred with the ancestors of Eurasians have been overcome,
thanks to a genome analysis method described in the April 2014 issue of the
journal Genetics. The technique can more confidently detect the genetic
signatures of interbreeding than previous approaches and will be useful for
evolutionary studies of other ancient or rare DNA samples. A new genome

"Our approach can distinguish between
two subtly different scenarios that could explain the genetic similarities
shared by Neandertals and modern humans from Europe and Asia," said study
co-author Konrad Lohse, a population geneticist at the University of Edinburgh.
The first scenario is that Neandertals occasionally interbred with modern
humans after they migrated out of Africa. The alternative scenario is that the
humans who left Africa evolved from the same ancestral subpopulation that had
previously given rise to the Neandertals.
Many researchers argue the interbreeding
scenario is more likely, because it fits the genetic patterns seen in studies
that compared genomes from many modern humans. But the new approach completely
rules out the alternative scenario without requiring all the extra data, by
using only the information from one genome each of several types: Neandertal,
European/Asian, African and chimpanzee. The same method will be useful in other
studies of interbreeding where limited samples are available.
"Because the method makes maximum
use of the information contained in individual genomes, it is particularly
exciting for revealing the history of species that are rare or extinct,"
said Lohse.
In fact, the authors originally developed
the method while studying the history of insect populations in Europe and
island species of pigs in South East Asia, some of which are extremely rare.
Lohse cautions against reading too much into the fact that the new method
estimates a slightly higher genetic contribution of Neandertals to modern
humans than previous studies. Estimating this contribution is complex and is
likely to vary slightly between different approaches.
"This work is important because it
closes a hole in the argument about whether Neandertals interbred with humans.
And the method can be applied to understanding the evolutionary history of
other organisms, including endangered species," said Mark Johnston,
Editor-in-Chief of the journal Genetics.

Since they did interbreed, leaving fertile offspring, it's obvious that Neandethals, Cro-Magnons, Java Man and the elusive Denisovians were not different *species* of humans but simply different *races*. They all interbred some 30,000 years ago to produce what we call modern man. The real question is, just when did the modern races begin differentiating?
