Scientists recently published the first footage of a sperm whale birth, and it was a crowded ordeal. More than 10 other sperm whales were there for the delivery and helped keep the baby whale afloat—and not all of them were related to mom. How much do we actually understand whale culture? And how should we think about altruism in the animal kingdom? Host Flora Lichtman chats with whale biologist Shane Gero about what it was like to witness this birth and what it tells us about whale culture. Guest: Dr. Shane Gero is a whale biologist at Carleton University, founder of The Dominica Sperm Whale Project, and biology lead for Project CETI. He’s based in Ottawa, Canada.
