Homo neanderthalensis first appeared about 200,000 years ago in Europe and existed until about 28,000 years ago. This was roughly the same time that Homo sapiens were living in Africa. It is believed that Homo neanderthalensis are descendants of the Homo heidelbergensis populations that were living in Europe prior to this time. Unlike Homo sapiens, H. neanderthalensis individuals had large brow ridges (the area above the eyes), larger and more protruding noses and faces, and were generally more compact to survive life in colder climates. Like H. sapiens, they had large or larger brains and used specialized tools, and there is some evidence that they created art and participated in symbolic or ritualistic behavior. There is evidence for occasional interbreeding between individuals of Homo neanderthalensis and Homo sapiens; as a result, many modern humans living today have a small amount of Neanderthal DNA in their genomes.
