NOVA S53E04 - Mammal Origins

Episode Overview

Explore the unexpected ancient beginnings of mammals, a saga that unfolded long before the age of dinosaurs. By examining Earth's chaotic history, we discover how early ancestors known as therapsids—reptile-like beings on the path to developing mammalian features—managed to endure numerous global disasters. Their incredible adaptations, such as burrowing and becoming warm-blooded, allowed them to create a lasting legacy. With the help of intriguing fossil evidence and advanced scientific insights, we learn how a small, tenacious group of animals survived extinction events, outlasted colossal creatures, and eventually led to the rich variety of mammals we see today, including ourselves.
