Some of the human X chromosome originates from Neanderthals and is found exclusively in people outside Africa, according to an international team of researchers led by Damian Labuda of the Department of Pediatrics at the University of Montreal and the CHU Sainte-Justine Research Center. The research was published in the July issue of Molecular Biology and Evolution.
"This confirms recent findings suggesting that the two populations interbred," says Dr. Labuda. His team places the timing of such intimate contacts and/or family ties early on, probably at the crossroads of the Middle East.
Neanderthals, whose ancestors left Africa about 400,000 to 800,000 years ago, evolved in what is now mainly France, Spain, Germany and Russia, and are thought to have lived until about 30,000 years ago. Meanwhile, early modern humans left Africa about 80,000 to 50,000 years ago. The question on everyone's mind has always been whether the physically stronger Neanderthals, who possessed the gene for language and may have played the flute, were a separate species or could have interbred with modern humans. The answer is yes, the two lived in close association.
"In addition, because our methods were totally independent of Neanderthal material, we can also conclude that previous results were not influenced by contaminating artifacts," adds Dr. Labuda.
Dr. Labuda and his team almost a decade ago had identified a piece of DNA (called a haplotype) in the human X chromosome that seemed different and whose origins they questioned. When the Neanderthal genome was sequenced in 2010, they quickly compared 6000 chromosomes from all parts of the world to the Neanderthal haplotype. The Neanderthal sequence was present in peoples across all continents, except for sub-Saharan Africa, and including Australia.
"There is little doubt that this haplotype is present because of mating with our ancestors and Neanderthals. This is a very nice result, and further analysis may help determine more details," says Dr. Nick Patterson, of the Broad Institute of MIT and Harvard University, a major researcher in human ancestry who was not involved in this study.
"Dr. Labuda and his colleagues were the first to identify a genetic variation in non-Africans that was likely to have come from an archaic population. This was done entirely without the Neanderthal genome sequence, but in light of the Neanderthal sequence, it is now clear that they were absolutely right!" adds Dr. David Reich, a Harvard Medical School geneticist, one of the principal researchers in the Neanderthal genome project.
So, speculates Dr. Labuda, did these exchanges contribute to our success across the world? "Variability is very important for long-term survival of a species," says Dr. Labuda. "Every addition to the genome can be enriching." An interesting match, indeed.
>>So which is it... Neanerthal or Neandertal?<<
Neanerthal.
Neaner, neaner, neaner!!!!!
Yes, but still the overall genetic differences are very small. All different races can have offspring with each other.
There´s good evidence that Neanderthals put flowers into the graves of their dead, who were also purposely buried. I wouldn´t mind being linked to those who practiced among the earliest of religious rites.

I have to ask (again) is the media TRYING to start a race war? They have happily helped to put America into the position we are at now. Seems like all they have left to do is incite us into a civil war.
Don't worry, "Uncle Baraq" knows some people who can fix you up with a COB.
Take Back AMERICA!
FUBO GTFO 2012 !
“So, speculates Dr. Labuda, did these exchanges contribute to our success across the world? “ “Every addition to the genome can be enriching.”
He seems to be arguing for the success of non-African populations- those that had cross bred with the Neanderthal line. The doctor must look out, the PC police may cometh.
Nephilim may be more accurate.................
Location, location, location...and good or bad...African is the PURE race.
Maybe Neanderthals are the children of Nephilim................
Additional useless bit of trivia. Our word "dollar" comes from "thaler" or "taler," which was a mediaeval coin minted in (and with silver mainly from) the Joachimsthal, in Bohemia.
Well, a little problem with that view, Noah and his kin were supposedly pure blooded and everyone else supposedly died in the flood. Unless he included a pair of First Persons in the ark.
True, but those genetic differences make sub-Saharan (euphemism for black) Africans a separate subspecies of Homo sapiens sapiens (anatomically modern humans).
Subspecies is either a taxonomic rank subordinate to species, or a taxonomic unit in that rank. Organisms that belong to different subspecies of the same species are capable of interbreeding and producing fertile offspring.
Neanderthals were also a subspecies of homo sapiens (homo sapiens neanderthalensis). This evidence proves they were capable of interbreeding with homo sapiens sapiens.
Don't you mean 'ethnicities'? There's only one race, the Human one. Every other distinction is local and only amounts to variation of the basic type.
Totally agree, what happened to the Neanderthals? We are the Neanderthals! Modern humans and Neanderthals interbred to create us. Which ever group discovered fermentation first should be given credit.
Maybe, but some of my old apps are no longer working.
“Sheila Jackson Lee....
Now THERE is evidence of a more evolved breed of human!”
DEVO was right!
“Are we not men?”
Ah yes. Gen 6:4: "...heroes of old, men of renown"
Because I have a double X ... I demand double monthly compensation.
