Sep 16, 2026 · 25m
Summary
Paleoanthropologist Dr. Johannes Haile-Selassie discusses his journey from history to discovering key hominid fossils like Ardi and Arti. He explains the fieldwork of surveying the East African Rift, where geological erosion exposes ancient sediments, and emphasizes the importance of training one’s eye to spot small fossils. The conversation highlights the shift toward data sharing and community engagement in the field, as well as how modern genetic analysis is revealing "ghost" ancestors and deepening our understanding of human evolution.
