Olduvai Gorge

The Olduvai Gorge, popularly referred to as “The Cradle of Humankind”, is the site where in 1959 Dr. Louis Leakey discovered the skull of Zinjanthropus or “Nutcracker Man” believed to have lived 1.75 million years ago. Later reclassified as Australopithecus boisei, this creature had a massive skull though small brained (500 cc) with huge teeth. Several months later Dr. Leakey found another fossil hominid in the same layer of excavation, called Homo habilis or “handy man”, smaller than the “Nutcracker Man” but with a larger brain (600 cc) and capable of making simple stone tools.
