Certain fields of science attract broad interest because of what they tell us about humanity, and no field does this more directly than paleoanthropology. Today we explore the history of paleoanthropology with a focus on Louis and Mary Leakey, who made key discoveries at an inflection point of our understanding of human evolution. With us to discuss this history is Evan Hadingham. Evanis the Senior Science Editor of the award-winning PBS series NOVA. Today we discuss his new book, Discovering Us, Fifty Great Discoveries in Human Origins, published in partnership with the Leakey Foundation in 2021.
