Neanderthals and modern humans interbred, probably when early humans decided to migrate out of Africa., according to a genetic study released. People of European, Asian and Australasian origin all have neanderthal DNA, but not Africans, researchers reported.The study may help resolve the long-running debate whether neanderthals and modern humans did more than just live side by side in Europe and West Asia.While the finding may lead to jokes about cave man behavior or looks we could not find any neanderthal 'traits'. "As far as we can tell, these are just random pieces of DNA." ,he said.The researchers used modern methods calls wholde genome sequencing to examine the DNA from neanderthal bones found in Croatia, Russia, Germany and Spain, including some crushed leg bones from one Croatian cave that some scientists believe are evidence of cannibalism.They compared the neanderthal sequences to DNA sequences from five people from Europe, Asia, Papua New Guinea and Africa. The results add a picture of modern humans living alongside with and interacting on the most intimate levels with similar humans who have not gone extinct.The DNA sequences date back to somewhere around 80,000 years ago, when modern humans moving through West Asia on their way out of Africa would have encountered the southernmost populations if neanderthals.The researchers identified five genes unique to neanderthals including three skin genes.
