The Neanderthal in You

A surprising new discovery has found that 1 to 4 percent of the DNA of present day humans comes from Neanderthals. This is due to breeding between modern humans and Neanderthals, which lived predominantly on the Eurasian continent until disappearing approximately 28,000 years ago. It was previously thought that human genes came nearly entirely from the African tribes which are our direct ancestors. In fact, the scientists who conducted the study claim to be shocked at the outcome, reporting that they were strongly biased against this idea before seeing the results.
