Mice, rats, beavers, and more! Rodents are some of the most diverse and successful mammals on the planet. This episode, we discuss what traits make rodents special, and we explore their incredible living diversity. Then we’ll take a trip to the past to investigate early rodent evolution, some highlights of their fossil record, and some of their ancient competitors.
