Episode 249 - Sexual Dimorphism

In most animal species, there are differences in the anatomy, behavior, and lifestyle of male and female individuals. In this episode, we explore the incredible variety of these differences and the equally incredible blurry areas between the sexes, we investigate the evolutionary processes behind these features, and we examine the constant and confounding discussion about whether or not we can spot sexual dimorphism in the fossil record.

In the news: The Story of Birds, early snakes, and early archosaurs.
