....Neanderthals had been around for about 30,000 years when modern humans appeared in the fossil record about 200,000 years ago. Neanderthals disappeared about 30,000 year ago. In 2010, scientists completed the first sequence of the Neanderthal genome using DNA extracted from fossils, and an examination of the genetic material suggested that modern humans' ancestors occasionally successfully interbred with Neanderthals. Recent estimates reveal that Neanderthal DNA makes up 1 percent to 4 percent of modern Eurasian genomes....

Don't Panic.
