Genetic research confirms that non-Africans are part Neanderthal
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.

At the very least asian students consistently outperform European and American students. and I do remember a study in which the average Israeli scored particularly well on intelligence test.
That said: Waging wars isn't about intelligence but about empathy. And in the prospect politicians the world over are sorely lacking.
What has that got to do with intelligence? Consider South and North Korea. Basically the same genetic heritage and - presumably - under the same nurture conditions the same level of intelligence. One lives in democracy the other does not. Wanting a democracy can often be denied by enough bullets. this has nothing to do with intelligence.
That explains a lot...

I can only draw from the standards I saw at US schools (having lived there for two years). There was a very obvious layered structure in the statistics for the honors students: At the top students from Asia, then those from Europe, then American, then Hispanics.
This impression seems to be corroborated by the PISA study

Here it seems quite clear who holds the top spots in Math, science and reading comprehension (There's also the TIMMS study in which the US did a bit better - mainly because many of the top performing countries of the PISA study didnt participate)

As with everything IQ is a nature AND nurture thing.
What I stated was:
"Asians outperform the rest of the world in standardized tests."
Nowhere did I mention that this was due to genetic superiority. That someone can be bred to be genetically/intellectually inferior was YOUR statement (as regarding North Korea) - not mine.
I simply noted that this seems to be reflected in the honors roll. My private suspicion is that this is due to the different attitudes of Asians, Europeans and Americans when it comes to education.

Asian friends would study and study until they got 100% of the material down and _understood_ before going into a test.
School certainly isn't about the noble pursuit of knowledge for _any_ kid (nor about social status). It's about passing tests.
We only find out later that that helped us a whole lot and that knowledge and understanding has value which is (and was) worth the effort.

If that's supposed to be a universal statement (there's no kid who visits school for the pursuit of widening her/his knowledge) then you are wrong.
Poor pupils whose social contacts are severed (by whatever) do sometimes find their ultimate reward in amassing knowledge. Their best friends are books. They are not afraid of tests as tests are a pleasing variety for them.
Of course, in a world of TV and internet, this species is becoming increasingly rare.

Wurd up-
-As neandertals were better adapted to temperate conditions, biologically they may have been seen as favorable mates for producing better-adapted offspring. Biologically-speaking that is. There may just be unconscious motivators for selecting mates based on the chance that offspring might fare better in new environments.
Over hundreds of gens neandertal morphology and metabolism had been selected for cooler climates. Their mating may have even become seasonal. Tropical pioneer groups would have had an easy way of incorporating these adaptations instead of developing them themselves. This selection mechanism may be genetic.
It may have also been the source of considerable neandertal animosity toward tropical interlopers, as the offspring of such pairings would be less well-adapted and less apt to survive.
This may have something to do with racial tensions in todays world. Unfortunate but from a biological standpoint, understandable.

THIS white knuckle-dragger doesn't care about anyone's ethnicity. Seriously, genetic heritage doesn't mean a thing to me. I'd say it "pales in significance" compared to behavior, except that someone would misunderstand, so instead I'll phrase it as "actions are what matter". It isn't what color, shape, or gender you are that matters. It is what you DO.
On aggregate I'm talking "culture". "Culturalist" isn't a bad name like "racist", and I'll make no apologies about preferring my own culture, nor get my feathers ruffled if someone prefers theirs. I'm not saying "all cultures are equal". But just because I think some cultures are an abomination doesn't mean a thing about the physical heritage of the people in those cultures.
Historical genetic research doesn't support political advocacy for either the left or right, and I'd hope the researchers would be offended if their study was used to support racism.

I stand by that statement of a day or two ago and yes, it is probable that despite its vast cosmopolitan/multiculturalism, a desperate Germany, fighting through a depression and paying megatons of reparations may have witnessed a poisoned element of racism in its midst. The point some political element SHOULD have made at the time is that even though the Jews do tend to 'stay to themselves' they are bearing their fair share of the pain and sorrow of Germany. Germans HAD BEEN culturally tolerant moderates.

Ok, now to continue, this is before race, back when we were all just the human race fighting nature for survival. Cultures and countries had not been founded yet.
First a neanderthal created a painted bead out of a shell. It is the earliest art known to man predating homo sapien entry into europe. The only ape present was neanderthal. So we know he made it. Next, we have cavemen and interbreeding. Which is followed by a slow change in neanderthal culture and a decline in large tool culture (actually more effective than micro tool culture brought from Africa by homo sapien.) This is time period includes cave paintings cave living hunting gathering nomadic culture for all. This time period also includes the first religion the snake cult of Botwana.

An example of the high mindedness of scientific research that often gets science in general in so much trouble.
The actual proof of this being true was the "lack" of proof it happened, NOT proof that it was impossible.
To some it just seemed so common sense, speaking of it as proven would cause no harm at all, because their opinion would eventually be verified.
Riiiiight.
The # of climate denialists grow for this very reason.
Considering how different species far different from each other can naturally interbreed, why the notion that a Cro-Magnon/Neanderthal hybrid was impossible seem common sense always seemed daft to me.
I always noted that scientists who said it was impossible were almost always Americans. I'm not surprised who found out otherwise.
