Abstract
As long as 160,000 years ago, people who looked like modern humans roamed Africa. For more than 100,000 years, these populations remained small in number and were confined largely to Africa. Approximately 50,000 years ago, despite no apparent physical change, a subset of these people dramatically altered their behavior, producing the first artifacts unequivocally deemed to be jewelry and inventing new technologies, such as projectile weapons, that allowed them to fish and to hunt dangerous prey. Over the next 15,000 years, these Stone Age hunter–gatherers spread from Africa to Europe, and, wherever they appeared, the Neanderthals, who previously inhabited Europe, rapidly disappeared.
