Genetic research confirms that non-Africans are part Neanderthal
University of Montreal ^ | July 17, 2011 | Unknown

Posted on 07/18/2011 7:16:57 AM PDT by decimon

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.

This seems to be about a millimeter away from saying that blacks are less evolved than (or "evolved differently from")whites.

This research indicates that there is a very significant genetic difference between the black and non-black populations.

The researchers need to watch their backs, once the non-politically-correct implications of this are thought about.

"An X-linked haplotype of the Neandertal origin is present among all non-African populations"

The absence of Y-linked genetic material implies that descent is entirely through mating of Cro-Magnon males with Neandertal females. This would be consistent with Cro-Mags killing off the Neandertal males and taking the females.

The inverse hypothesis ("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. The truth appears to be somewhere in between.

Significant to whom?

And [God] hath made of one blood all nations of men for to dwell on all the face of the earth, and hath determined the times before appointed, and the bounds of their habitation;
Acts 17:26

So, would you not take the blood of an African descendant if you needed surgery?

Brings to mind an Archie Bunker show where he found out that the blood he received for surgery came from a Black person.

Also brings to mind the complete title for Darwin's tome.

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.

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...)

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?

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.

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.

I've worked with people of all races who happen to be smarter than me, as well as people of all races who were complete idiots. I think Thomas Sowell is a much smarter man than anybody in this discussion.

That said, it's hard to argue against the existence of STATISTICAL differences that don't seem to go away no matter how much money you throw at the issue.

You don’t believe that the Bible is God’s Word, so you do not believe Paul was speaking for God.

I already got that, in case you missed it.

You refuse to recognize “blood” in the context here in which it is used, to denote ancestry or kin, a use very common throughout the ages in the English language as well as many others.

I already got that, too.

You are just repeating yourself, and I am repeating myself now, so I think our discussion is over.

I do believe in God’s word, just that Paul wasn’t speaking for God.

I gave you the context from the Concordance, based on the word that Paul used. You on the other hand are blowing smoke and putting a meaning to the word that wasn’t intended.

Have a nice day.

they were not raised in the same household...

the first was raised in a household by new parents who had a single child...

the next child was born to a set of doting parents and a jealous older sibling...

the third had parents who were non-chalant about childhood traumas of a child that not only was tormented for now being the favorite, but received the hostility of not one but two older siblings...

it is pretty much all nurturing...

bless you for your parenting.

Any research or discussions about bio-determinism are too scary to be handled for most universities. What’s needed is objectivity, facing who and what we are physically and spiritually, all differences and similarities. None of our educational, criminal, political problems can be solved until we are willing to face the whole truth about who we are and our origins.
