Researchers from the Museum of Human Evolution and the Natural History Museum in the UK have developed a new
Although about 2% of the DNA of all people descended fromthose who live outside of Africa make up the Neanderthal genome, so far not a single fact has been revealed when late Neanderthals (who lived from 40 to 60 thousand years ago) would have traces of the genetic material of the ancestors of modern people, the researchers note.

They believe it is process related.hybridization: it has been proven that some species are able to produce offspring only in certain directions. For example, pollen from the plant Capsella rubella can successfully fertilize the seeds of Capsella grandiflora, but not vice versa.
Because mitochondrial DNA (whichpassed on from the mother) modern humans have no traces of Neanderthals, researchers believe that only Neanderthal males and Homo sapiens females could mate.
Because there were fewer Neanderthals,than Homo sapiens, and the groups of these people were more distantly distributed, hybridization outside of family groups could contribute to the decline of this species, the scientists note. The researchers hope that further genetic research, including genome sequencing from ancient human remains found in various areas, will help confirm this hypothesis.
