Summary

Every plant starts somewhere, and often that somewhere is inside a seed. Seeds are among the most diverse and important evolutionary innovations of plants, allowing species to survive, thrive, and travel between generations in extraordinary ways. This episode, Aly joins us to discuss how seeds do what they do, how seeds have evolved over time, and how seeds are invaluable resources for paleontologists seeking to understand plants of the past. In the news: early octopus-cousins, early tuatara cousins, evolution of walking, and how sauropods moved.
