Are forward-looking humanity the hybrid child of other mankind and Neanderthals ? For over a tenner , scientists have question what incisively happened to the Neanderthals , low - technical school hominids who populate Western Europe , when homo sapiens arrived on the scene from Africa and Asia with sophisticated weaponry and the rudiments of symbolic artistic production . Homo sapiens arrived in Europe close to 45,000 years ago , and co - existed with Neanderthals for what scientist estimate could have been anywhere from 1000 to 10,000 years . Some remains seem to suggest that the two groups shared the same caves , and might have swap with each other . But what else did they deal ?
Though we ca n’t be certain what their everyday interaction were like , scientists now have one more art object of grounds that homo sapiens and Neanderthals were n’t commix their DNA .
A group of Italian researchers put out a young study today in PLoS One liken the deoxyribonucleic acid from former human bones from about 28,000 years ago with DNA Neanderthal bones . What ’s coolheaded about the Modern study is that the early human bones are quite recently discovered , and therefore very unlikely to have been contaminated by DNA from humans who have handled them .
The researchers sequence desoxyribonucleic acid from these bones , testing to see if there was significant overlap with Neanderthal DNA , which would argue that homo sapiens ’ DNA had been change by interbreeding with Neanderthals . Many anthropologistshave long believed that the two species interbredbecause there are a few ancient skulls whose syllable structure seems to be a everlasting portmanteau of human and Neanderthal .
But trial run of the fossilized DNA revealed no couple . The early human DNA from the Italian researchers ’ sample looked very much like innovative DNA , not like Neanderthal deoxyribonucleic acid . So it look like human were n’t commence busy with Neanderthals after all . Or if they were , they did n’t have a fate of baby .
