The modern country of Jordan is within the eastern or inland Levant, a region that has undergone striking cli- matic and ecological change during the course of the approximately 450,000 years of its Palaeolithic prehistory. Its story of ancient humans is one told largely through the stone tools they discarded, their campsites, the remains of their food, and the reconstruction of the landscapes they inhabited. More rarely, this story also includes evidence from burials and of artistic expression. The study of these Palaeolithic groups and their lifeways is part of a research tradition with a lengthy history, one which has acceler- ated at a dramatic pace since the 1970s.
