Penguins aren’t the only flightless birds, and they aren’t the only diving birds, but they sure are good at doing both! In this episode, we discuss modern penguins’ unique suite of adaptations that allow them to spend so much of their lives in the water, and then we address some of the most pressing questions about their past: How did they get their start? What drove their evolution? And why were some of them so disconcertingly large?
In the news: giant coelacanths, really old DNA, fossil vampire squid, and dinosaur ecology.
