"Europe, not Africa, might have spawned the first members of the human evolutionary family around 7 million years ago, researchers say. The scientific consensus long has been that hominins originated in Africa. This is not helped by the fact that the Greek jawbone - nicknamed El Graeco - has a heavily worn surface. However, researchers analyzing two fossils - a jawbone from a German museum and an upper premolar from a collection in Bulgaria - concluded their ages to be roughly 7.2 million years, and belonging to a pre-human. "Our research shows that the earliest humans may have evolved in Europe"."
