Ella al-Shamahi is one part Charles Darwin, one part Indiana Jones. She braves war zones and pirate-infested waters to collect fossils from prehistoric caves, fossils that help us understand the origin of our species. Her recent hit BBC / PBS series Human follows her around the globe trying to piece together the unlikely story of how early humans conquered the world. But Ella’s own origins as an evolutionary biologist are equally unlikely. She sits down with us and tells us a story she has rarely shared publicly, about how she came to believe in evolution, and how much that belief cost her.
