Episode 63 - Sexual Selection
Episode description
The history of animal life on Earth has been shaped by sex. The struggle to reproduce puts unique evolutionary pressures on species which affect their behavior and even their physical form. Sexual selection is immensely important but trying to sort out the side effects of sex in the fossil record is notoriously tricky.
In the news: giant beavers, croc metabolism, schooling fish, and another new croc.
