The researchers have been rewarded with human fossils – to date, three skulls around a million years old. The first close human lookalike appeared in Africa around two million years ago in the form of Homo erectus. What does this mean for other human fossils we have found? If Neanderthals, Denisovans and sapiens evolved away from each other a million years ago, there must have been earlier human forms not yet seen. If early Homo sapiens evolved a million years ago, as this study suggets, when did individuals start to make art?
