Around 100,000 years ago there was another species of the Homo genus living throughout Europe, <span>he <span>Homo <span>neanderthalensis</span></span>,</span> or commonly called the Neanderthals. This extinct species was the closest relative to modern humans. Genetic studies of neanderthal DNA have shown that in modern humans that live outside of Africa there are3 to 4 percent of genes that have a neanderthal origin which implies that there were multiple interbreeding events in the history of these two species.
