Neanderthals got the short end of the stick from their trystswith humans, who drove them to extinction 30,000 years ago, but the benefits of interbreeding between the two groups live on.According to new research in Science Journal, sexual relations between ancient humans and their Neanderthal cousins produced offspring with immunity genomes that scientists say still exist in modern human DNA. Previous research indicated prehistoric inbreeding was responsible for 4 percent of the human genome.
