They report that the fossil These fossils are of interest for their potential to Apidima 1 is an H. sapiens specimen that is at least 210,000 years old, from a time when Neanderthals reveal how many hominin species might have occupied many European sites. It is the earliest known example of H. sapiens in Europe, and is at least lived during this time. Perhaps some of them 160,000 years older than the next oldest H. sapiens fossils found in Europe6 (not shown). Harvati and 7 are also H. sapiens, although I doubt it. Among colleagues confirm that, as previously reported , Apidima 2 is a Neanderthal specimen, and they estimate the most complete of these specimens are that it is at least 170,000 years old. The authors’ findings, along with other discoveries of which a selection crania from India at a site called Hathnora15, is shown here, shed light on the timing and locations of early successful and failed dispersals out of 16 16 and from China at Dali , Jinniushan and Africa of hominins (modern humans and other human relatives, such as Neanderthals and Denisovans). 17 kyr, thousand years old.
