In 1999, I visited the Rift Valley in East Africa and sketched the Olduvai Gorge where Louis Leakey, his wife and family members scratched and dug out the earliest ancestors to humans. It is good to see that the family is carrying on the tradition of asking: "Who are we?"

This video is part lecture on the elements of anthropology, part family slideshow telling the story of a girl who grew up hunting bones with her mom and dad.

Louise Leakey is the third generation of her family to dig for humanity’s past in East Africa. In 2001, Leakey and her mother, Meave, found a previously unknown hominid, the 3.5-million-year-old Kenyanthropus platyops, at Lake Turkana -- the same region where her father, Richard, discovered the "Turkana Boy" fossil, and near Tanzania’s Olduvai Gorge, where her grandparents, Louise and Mary Leakey, discovered the bones of Homo habilis.
In August 2007 Louise and Meave, both National Geographic Explorers-in-Residence, dug up new H. habilis bones that may rewrite humanity's evolutionary timeline. We imagine that we evolved from apes in an orderly progression from ape to hominid to human, but the Leakeys' find suggests that different species of pre-humans actually lived side by side at the same time for almost half a million years.
