20% of Neanderthal Genome Survives In Humans
vinces99 writes "A substantial fraction of the Neanderthal genome persists in modern human populations. A new analysis (abstract) of 665 people from Europe and East Asia shows that more than 20 percent of the Neanderthal genome survives in the DNA of this contemporary group, whose genetic information is part of the 1,000 Genomes Project."
Another study published today (abstract) finds that Neanderthal genes are present in some parts of our genome that we've found to be important. Some of the genes influence fertility and skin pigment, and others actually increase our susceptibility to diseases like diabetes and lupus. The researchers are now taking these known genetic markers and seeing if they correlate with any other health conditions.
I thought they meant "fertility skin pigment" to mean coloration of certain reproductive parts.
But they probably just forgot a comma.
You replicate those genes by 3d printing, and offer them for bitcoins, and that's how you end up on slashdot.
Fuck systemd. Fuck Redhat. Fuck Soylent, too. Wait, scratch the last one.
I'm surprised it's not higher.
Fitting article for SuperBowl week.

In some more than in others. ;)
I may be 20% neanderthal, but I'm statistically 0.5% Genghis Khan...
I'm 3.2% according to 23andme.
Have you tried turning it off then on again?
These genes do not exist in humanity in general, only specific racial groups. They are completely absent from African populations. Similar to milk digestion. Being able to digest milk in adulthood is a feature found almost only in European race populations, because it is allowed by a genetic mutation that occured in these populations 10,000 years ago. Most other racial groups are lactose intolerant after early childhood. Milk digestion in adulthood is certainly a huge advantage and became much favored with cattle domestication in Europe.
The insertion of neanderthal genes happened around 30,000 years ago immediately after early humans left africa, after that there were 30,000 years of divergent evolution and branching that gave us the geographically distinct racial groups.
20% of people are nigger's. Coincadanse I think not.
Apparently your have more Neanderthal genes than the average. You obviously are too stupid to know how to spell or turn on your OS's spell checker.
It's really quite a simple choice: Life, Death, or Los Angeles.
Not surprising really. Human fetuses have tails in the early stages.
Neanderthals are barely a separate species.
They're homo neanderthalensis, while modern man is homo sapiens sapiens. The immediate predecessor to modern humans is homo sapiens idaltu, which is minutely different than us. While a simple majority of paleontologists classify Neanderthals as a separate species, there's a significant minority that advocate them as merely another subspecies (home sapiens neanderthalensis) being more correct.
Given that the ENTIRE Neanderthal genome differs from ours by 0.15% or less (we're about 2% different than our closest modern primate relative), I'm very surprised that the Homo-specific genome part is only 20% in common between Neanderthal and Modern Human. Particularly since it's now commonly accepted that they interbred with modern humans.
I think the 20% commonality (if it bears out) probably reinforces the "separate species" theory more than the "distinct subspecies" theory of the Homo genus family tree.

There are always four sides to every story: your side, their side, the truth, and what really happened.
I've always found the neanderthal theory of autism interesting. Like, I know there's little to no actual evidence, but I can totally see it happening!
tada!
What I find interesting is the only group that doesn't have Neanderthal genes are Africans. It almost sounds like Caucasians got their light skin and ability to handle the cold from Neanderthals and are hybrids while Africans are the only pure humans. Ironic.
It would be like /. designing tests for literature majors.
How do they know this conclusively? Mightent the other 80% be identical to human genome?

[Sigh] Still deciding. I mean, the codebase is starting to look a bit creaky in a few places, and they're starting to tinker with it themselves (they think it's open source - hah!). Inquisitive little so-and-so's can't leave well enough alone... They've noticed the legacy code from the previous build too - ick, some cruft in there. Very tempting to trash the lot and start again using AOP. Mind you I mightn't have to lift a finger if they don't stop blowing each other to smithereens.
[sigh] TODO: Take oort cloud inventory - look for something nice and big...
GIven that neanderthals were the pale-skinned ones, that's probably a good bet. We can only hope that he does all he can to prevent his own shameful neanderthal genes from being propagated to future generations.
And thank you for following Skitt's Law.

The "bowels" have it!
For instance an average European has an average IQ of 105 compared to 70 in Africa. Though, the higher IQ is likely due to divergent racial evolution that occured well after the insertion of neanderthal genes...
Or it could be a matter of education, relative stress in childhood, and diet. Or it could be a matter of a cultural upbringing that doesn't value and train people in the types of reasoning favored by IQ tests. I'd like to see a test cataloging our relative abilities to navigate vast terrain, to remember and recite oral histories, to perform pattern recognition based on ability to identify wild plants, or just a simple ability to navigate complex social situations, for example. Or it could be a function of languages, since we already know that languages can affect things like the ability to recognize and categorize colors.
Have you ever read letters from American Civil War soldiers to their families back home? We're not talking a college education demographic by a long shot, but the eloquence and care of language in these letters is often breathtaking. Are we "dumber" than them as a populace for not being able to write like an average farm boy could 150 years ago? Or are we just trained for different uses of our brains.
IQ is a crappy measure of genetic superiority, because it fails to account for environment & upbringing, and it's heavily biased towards one particular culture's most valued intelligence traits.
If it's for-profit but free, you're not the customer -- you're the product (e.g., the Slashdot Beta's "audience").
A full 15% of the 20% is in Ozzy Osbourne's family tree.
Papa was a rolling stone.
I think they're referring to the section of our DNA which is specific to the Homo genus.
That is, DNA for the Homo genus is probably about 99.5% or more in common, across all species of Homo. You can tell where the Homo DNA starts by comparing it to other members of the subfamily Homininae, and looking for differences.
So, in the Homo-specific portions of our DNA, TFA is claiming that 20% or so is common to modern humans and Neanderthals. That still seems low, given the interbreeding of Neanderthal and Modern Humans, and the fact we both share a direct common ancestor.
Africans have no neanderthal DNA while Northern Europeans and East Asians have the most...trouble in paradise, comrade?
For a good long time, anatomically modern humans didn't make cave paintings and jewelry either, at least not often enough to be detected. Nobody knows what triggered the use of art in humans.
The best theory I've heard is it's not that humans became smarter, but rather more social. Neanderthal brains were big if not bigger than ours, so they were potentially pretty smart. However, they may have been relatively anti-social.
The most successful humans were probably those who used trade to get the resources their area lacked. For example, your area may have good arrow-head rocks, but not a lot of prey during the dry season. If you encounter another tribe whose area has a lot of prey but poor rocks, you can trade rocks for meat, and both groups benefit and give birth to more traders instead of making war with neighbors.
Normally mammals battle neighboring groups because they compete with resources, so trade requires a different mentality: socializing with strangers. It may have taken several thousands of years to evolve this tendency. (Slashdotters are still working on it :-)
Neanderthals may just have been slower to take advantage of trade. This is possibly because the human population was greater, magnifying the benefits of trade.
Cave paintings and jewelry may have been an early form of advertising of your goods and services, and serving as social gestures of good will.

Don’t expect this “science” to sneak its way into the classrooms here in the South. Our Lord and Savior made it very clear there is no way we evolved from these savages. Tennessee has passed the Monkey Law legislation which ensures teachers can challenge these so-called scientists and their twisted research funded by the liberals in Washington. Read about how we’re keep Christ in the Classroom at http://dregstudiosart.blogspot.com/2012/04/pulpit-in-classroom-biblical-agenda-in.html
There were no neanderthals. Just ancient people who lived a lot longer so their bones look different. God created everything 6000 years ago. Watch Kent Hovinds videos.
...which is why, son, your dink

The article clearly indicates that the male offspring of Human-Neanderthal breedings might have had lower fertility or been sterile (because modern humans share very few sperm producing genes from Neanderthals). Hence it is far more likely that, Neanderthal males simply bred themselves out of existence by mating with human females, and the Neanderthalish male offispring of male Human to female Neanderthal matings never went anywhere. Thus the decreasing male Neanderthal ratio would force further matings of Neanderthal females with human males. Thus resulting in an eventual complete loss of male Neanderthals, and ever decreasing purity of Neanderthal females. Mystery solved.
In fact, 20% survive in Arnold Schwarzenegger alone. Add the National Football League, WWE Wrestling, and the Texas State Board of Education, and you've probably got well above 90%.
We all descended from aliens anyway.

actually i think it was designed to predict how well someone would do in the military, as the army were the originators of these tests and they used them when recruiting and tasking soldiers.

In India I think it's 80%. With a population of 1.25 Billion who have an avg IQ of 79, it just can't be 20%.
Neanderthals were most probably smarter. The theory is that they lived in small groups while our migrating ancestors lived in packs/tribes in larger numbers and until there was proof many people thought that they died off and were probably overrun. It was controversial to claim they bred until there was proof (but it's rather obvious if you think about it, people will screw anything - there is no way they wouldn't; no religion to stop them.)
India has a lot of poor uneducated people. If you lived and grew up like many of them did you'd be no smarter on a standardized IQ test.

BBC created an excellent documentary on neanderthals. They mature very quickly and younger aged neanderthals are fully developed mentally at a young age. They also retain aspects of youth for longer as a result.
I am sure my neighbor has more than 90% Neanderthal genome. Ironically he makes the same claim. Therefore it is obviously obvious that we must have a common neighbor that I am unaware of...
Ah. Now that neanderthal comment makes sense. I've been getting from time to time.
Considering that humans and chimps have over 95% identical genes, and the same is true for humans and gorillas and chims and gorillas I would assume neanderthals and modern humans have also about 95% - 99% common genes.
Where does this stupid 20% come from?

So were neanderthals not really human at all? I mean we share well over 90% of our DNA with monkeys, so where is this 20% figure for neanderthals coming from? Do they mean 20% of the 1% of DNA that is unique to humans?
