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.

About the study:
"An X-linked haplotype of the Neandertal origin is present among all non-African populations" was published in the July 2011 issue of Molecular Biology and Evolution. The authors are Vania Yotova, Jean-Francois Lefebvre, Claudia Moreau, Elias Gbeha, Kristine Hovhannesyan, Stephane Bourgeois, Sandra Be´darida, Luisa Azevedo, Antonio Amorim, Tamara Sarkisian, Patrice Hodonou Avogbe, Nicodeme Chabi, Mamoudou Hama Dicko, Emile Sabiba Kou' Santa Amouzou, Ambaliou Sanni, June Roberts-Thomson, Barry Boettcher, Rodney J. Scott, and Damian Labuda.
The study was supported by grants from the Canadian Institutes of Health Research.
I would say statistically significant.
Saying that different peoples have different abilities, as well as different looks, in no way implies that they have less moral worth as human beings. Nor does it imply they should have less worth legally.
The erroneous assumption that it does has poisoned racial discussion in the United States for decades.
I’ll see your three kids and raise the ante to four. As you say, “all raised in the same household, all different in their abilities and interests.”
We’re really not “Holder’s people.”
This sounds biblical to me.
Unfortunately there is more than one type of blood out there and they are not all compatible. Ever hear of A, A+, B, B+ or O? Then there is the RH factor.
Ok, let me get this straight. Scientist say that modern humans came out of Africa AFTER neanderthals died out. Therefore Africans have no Neanderthal DNA. However, how could any modern human have neanderthal DNA if they evolved from Africans? How are they determining “African” and “non African” populations? Did Europeans evolve separately from Afircans or didn’t they? Seems to me the DNA says they did.

How clever.
Unfortunately for you, blood types are not divided by Ancestry.
And I doubt that God was talking about blood TYPEs when stating that all are of ONE BLOOD, meaning ONE ANCESTRY.
PapaBear3625 didn’t say we aren’t “one blood”. he didn’t say we are different species.
but, there are genetic differences. even between black populations. sprinters from west africa, marathoners from east. causasian achilles tendons are different.
and the “Bell Curve” is ignored, but not refuted.
(just as Asians have HIGHER average I.Q. than caucasians.)
PC shouldn’t be allowed to trump science.
“(”there is no significant genetic difference and therefore all performance differences must be due to racism, which must be remedied”) isn’t turning out so well either. “
/// is correct. and spending billions to erase an “achievement gap” between caucasians and blacks, while ignoring the achievement gap between asians and whites, is simply wasting money on a false premise.

Is it a known absence or just one that wasn't looked for or no results, either positive or negative, were found. Also looking at the muscular structure of Neanderthals, it might be mating of Neanderthal females to Cro-Magnon males (Oooga likes that you have two eyebrows. You just hold still little man...)
God? I thought Paul said that.
I don’t mean to imply in the least that poor achievement in African descendants is attributable to “racism”.
However, there are many of African ancestry who have higher abilities than you or I, particularly athletic and musical abilities.
It’s time to celebrate our differences, not try to eradicate them, while recognizing our common humanity.
Hey, if I remember correctly, “valuing differences” was a Liberal idea. Whatever happened to that?
> God? I thought Paul said that.
Yes, of course, you must not believe that the Holy Spirit of God was inspiring Paul’s speech.
If you believe the Bible, then you believe we have a common ancestor.
That was the old theory. The new theory is that modern humans met up with neanderthals, and apparently interbred with them, before the pure neanderthals died out.
Maybe we should go back and ponder the significance of Genesis 6 1:8
I just looked and yep that was Paul not God and
http://www.blueletterbible.org/lang/lexicon/lexicon.cfm?Strongs=G129&t=KJV
Strong’s G129 - haima
1) blood
a) of man or animals
b) refers to the seat of life
c) of those things that resemble blood, grape juice
2) blood shed, to be shed by violence, slay, murder
Life is in the blood for both animals and man. Very generic. Nothing about ancestry.
Soknter...out loud!
So Canadians are stupid enough to pay for these worthless junk science studies, too. I guess that proves they are Neanderthals.
