The Brain Scoop: Mammalian Diversification

Person speaking. Caption: Well, today we're gonna talk about mammalian diversification.

Host Emily Graslie discusses a new scientific theory about mammalian diversification. According to this new theory, placental mammals evolved before a major mass extinction event, which occurred sixty-five million years ago. However, there is no fossil record to prove the new theory, but scientists around the world used genetic material to form their theory. Part of "The Brain Scoop" series.
