One hundred twenty-five thousand years ago, when the Sahara desert was savanna, with plentiful water and game, a group of hominids made tools under the protection of a rock overhang in Jebel Faya, United Arab Emirates. A German-led team argues of this week's issue of Science that these toolmakers were modern humans who may have crossed directly from Africa as part of a migration spreading across Europe, Asia, and Australia. Although most researchers agree that our species came out of Africa in one or more waves, those dates are more than 50,000 years earlier than most believe our ancestors left the continent.
