Olduvai Gorge, in northern Tanzania, is internationally recognized for Louis and Mary Leakey’s famous discoveries of early humans and magnificent antiquities documenting the evolutionary history of our stone tool-using ancestors, vertebrate fauna, and the environments over the last two million years.
Research at Olduvai began almost a century ago, producing an unparalleled wealth of archaeological and palaeontological data for the study of some key phases of early human evolution.
Olduvai was the first place where traces of an early stone tool culture were discovered, and gave the name to the Oldowan, nowadays considered as the earliest human technology. Olduvai is also one of the first sites in Africa where the earliest Acheulean was first discovered, and where the traditional view of the Oldowan-Acheulean transition was established.
The disappearance of the earliest human culture, the Oldowan, and its substitution by a new technology, the Acheulean, is one of the main topics in modern Paleoanthropology. The Olduvai Geochronology and Archaeology Project (OGAP) bring together an international team of archaeologists and geologists, whose main goal is to study the mechanisms that led to the origins of the Acheulean in Olduvai Gorge.
