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
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
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.
