Recent genetic studies have confirmed that at some time in the overlapping of their ranges, Neanderthals and modern humans interbred. Approximately 1-4% of the genetic material sampled from people from Europe, China and Papua-New Guinea originated from mixing with Neanderthals. Although no people of African descent sampled in the study possessed such material, researchers believe this is most likely the result of a limited sample size and that with more wide-spread testing Neanderthal genetic code will be found in other populations of modern humans living today.

Yes... It's true. :aok
:bolt:

Certainly this is no surprise to anyone..
Just imagine what our genetic code would look like if sheep were able to be fertilized....
... did I just trip over a line somewhere? :confused:

Nah...ugly twits throughout history have been trying to find suitable mates outside of their species...watching some of the wildlife walking the streets downtown...I suspect some successfully reproduced with nasty results.

How much money did 'they' waste figuring this out? :huh

That would certainly explain some of the posts.

This is the first report that I've seen that supports that conclusion. All prior genetic studies had been negative or inconclusive.
It should be noted though, that it is very hard to get Neanderthal genetic material.

Not according to the Lifetime channel...

History Channel started running a similar investigative show 3 months ago.

Previous studies had said there was no evidence, but while the possibility of interbreeding existed the offspring would be sterile (similar to the liger). However if this report is indeed true that would certainly not be the case any longer, as there's no way the genetic material of Neanderthals would be carried through to today in modern humans 30,000 years after the last Neanderthal died if the offspring couldn't reproduce.

I will just point out here that warring nations always have a certain amount of 'rape' going on. Not sure how 'they' conclude that actual offspring resulted that may not simply be abnormalities in gene structures (which is supposed to be the whole basis of Neanderthal as a human-subspecies). I call BS.

That was so easy, a caveman should have figured it out. :D :bolt:

The conclusion would be based on the existence of 1-3% genetic material matching Neanderthal genetic material that is present in Homo Sapiens populations in Europe and Asia but that is not found in sub-Saharan populations, per the story.

If this is true, it could prove that beer/alcohol was discovered during the early days of mankind.

Yes I watched the TWiS coverage today on it... Im not sure their mapping of Neanderthal genomes in the absence of actual Neanderthals is legitimate. Its a guess even if its an educated guess.
-
You can't map without material, not even a guess. My understanding is that we have recovered some Neanderthal DNA from teeth or dense bones where it lasts longer.
-
And can anybody tell us the % difference in our DNA makeup compared to a chimpanzee?
Karnak, we've had their bones since the 19th century. (According to HC) A skull I think.
-
We have a lot of their bones actually. But the conditions to preserve DNA for the 15,000+ years they have been extinct are pretty rare.
EDIT:
http://news.nationalgeographic.com/news/2005/08/0831_050831_chimp_genes.html
This story says 96% similar between Chimps and Humans. That would have been almost identical for Neanderthal, who are vastly closer to Homo Sapiens.
-
They are claiming similarities in gene chains indicate differences in Neanderthal and modern humans and somehow that because those differences are not common among Africans that cross-breeding must have occurred. You support that conclusion?
-
That sounds like what I had heard also. Now if you take a look at the anatomy, one could say the chimp & the neanderthal have a much closer similarity than ours to the neanderthal. Bigger chest cavity, wider hips, shorter legs and so on.

Challenge, I don't know enough about the claims to either support or dismiss them. I'd have to read the actual study, and my educational background is not biology, so I'd have to do a lot of cross studying to fully understand the report. I was just trying to clarify the basic claims and reasoning. Essentially they have found DNA chains in European/Asian homo sapiens samples that match chains found in neanderthal samples, but those chains were not present in sub-Saharan homo sapien samples.
Those differences are very slight compared to those differences between humans/neanderthal and chimps. Current evidence has chimps are much closer to the animal that is the common ancestor of hominids and chimpanzees and thus will bear a closer resemblance to early hominds, homo habilis for example. Neanderthal are millions of years downstream from that though.
Warning, throwing out rough numbers based on data remembered from classes long past:
Homo sapiens/Homo neanderthalensis and Pan troglodytes (chimps) nearest common ancestor would probably be found 5-10 million years ago. The nearest common ancestor for Homo sapiens and Homo neanderthalensis would be, perhaps, 500,000 years ago.

I think this is a VERY important finding of the study. Had this genetic coding been present in ALL modern humans sampled it could be considered an indication of a genetic relic retained from the last common ancestor between Neanderthals and Homo sapiens and not necessarily an indication of interbreeding between Neanderthals and modern humans. However what are the chances that genetic material found in ALL Neanderthals sampled are present in SOME populations of modern humans LIVING TODAY by coincidence or convergent development?
Granted, there's probably only a limited number of viable samples that were able to be collected from Neanderthal remains for the research but it still strikes me as significant.

Don't let it go, please explain why APDrone's comment's are quoted in mine? I never mentioned Lifetime..... The Channel for Women.

lol.. well, you do have an idea of what Lifetime is..
I figure they've been calling men neanderthals for years.. Since women are never wrong... Technically, all this DNA info is old news...
:salute

Oh, now they said that after all the studies of evolution i went through. Just wasted my 5 years of college.
