Zeresenay Alemseged is an Ethiopian paleoanthropologist who studies the origins of humanity in the Ethiopian desert, focusing on the emergence of childhood and tool use. His most exciting find was the 3.3-million-year-old bones of Selam, a 3-year-old girl from the species Australopithecus afarensis.

By studying these bones, Alemseged is helping us determine the timeline of human evolution — how we came to be and spread across the Earth, 7 billion strong.
