Med-trump writes: Neanderthals, whose ancestors left Africa about 400,000 to 800,000 years ago, evolved in what is now mainly France, Spain, Germany and Russia, and are thought to have lived until about 30,000 years ago. Now scientists have identified a piece of Neanderthal DNA (called a haplotype) in the human X chromosome and conclude that this haplotype is present because of mating with our ancestors and Neanderthals. The study was published in the latest issue of the journal Molecular Biology and Evolution.
