Rise of the Mammals

Sixty-six million years ago, an asteroid wiped out the dinosaurs in a fiery global catastrophe. But we know little about how their successors, the mammals, recovered and took over the world. Now, hidden inside ordinary-looking rocks, an astonishing trove of fossils reveals a dramatic new picture of how rat-sized creatures ballooned in size and began to evolve into the vast array of species.

PBS’ premier science series helps viewers of all ages explore the science behind the headlines. Along the way, NOVA programs demystify science and technology and highlight the people involved in scientific pursuits.
