Humanity’s expansion around the world from our African origins is astounding. How did we spread across the globe? Why do people from different regions vary? Is our diversity a function of geography, adaptation, or both? In this lecture, Leakey Foundation grantee Alexander Harcourt explores how humanity’s interaction with the environment can explain why we differ biologically and culturally from one region of the world to another. “Humankind: How Biology and Geography Shape Human Diversity” was presented at the California Academy of Sciences on 5/9/2017 as part of The Leakey Foundation’s Speaker Series program in partnership with the California Academy of Sciences.
