It is still debated, however, whether these hominids belong in their own species, Homo neanderthalensis, or represent an extinct variant ofHomo sapiens. Our ongoing studies indicate that the Neanderthals differ from modern...

The Arabian Peninsula was the initial site of the out-of-Africa migrations that occurred between 125,000 and 60,000 yr ago, leading to the hypothesis that the first Eurasian populations were established on the Peninsula and that contemporary indigenous...
