What’s significant about Mary and Louis Leakey?
Paleoanthropologist Louis Leakey, with wife Mary Leakey, established an excavation site at Olduvai Gorge to search for fossils. The team made unprecedented discoveries of hominids millions of years old linked to human evolution, including H. habilis and H. erectus.
What was Mary Leakey’s theory?
Among several prominent archaeological and anthropological discoveries, the Leakeys discovered a skull fossil of an ancestor of apes and humans while excavating the Olduvai Gorge in Africa in 1960—a find that helped to illuminate the origins of humankind. Mary continued working after her husband’s death.
How did Mary Leakey meet Louis?

Mary Leakey/Age at death
Mary Leakey, matriarch of the famous fossil-hunting family in Africa whose own reputation in paleoanthropology soared with discoveries of bones, stone tools and the footprints of early human ancestors, died yesterday in Nairobi, Kenya. She was 83.
How were the Laetoli footprints dated?
The Laetoli footprints are rare treasures in the record of human ancestry. Volcanic rock — like the trail at Laetoli — can be dated by a method called potassium-argon dating. Hot, newly erupted lava and ash contain a form of the chemical element potassium (called potassium-40) that is radioactive.
Who paid for much of the Leakeys work?
