 Hadzaland is just from Olduvai Gorge, an area sometimes called the "Cradle of Mankind" because of the number of hominin fossils found there, and from the prehistoric site of Laetoli.Archaeological evidence suggests that the area has been continuously occupied by hunter gatherers much like the Hadza since at least the beginning of the Later Stone Age, 50,000 years ago.Although the Hadza do not make rock art today, they consider several rock art sites within their territory, probably at least 2,000 years old, to have been created by their ancestors, and their oral history does not suggest they moved to Hadzaland from elsewhere.
