What has hair, special ear bones, gives birth to live young, and can be found all over the world in all shapes and sizes? Mammals, of course!

Posed from the floor to the ceiling, the animals in this exhibition range from the familiar Eastern gray squirrel to the rare okapi, a central African mammal so shy scientists didn’t know it existed until the early 1900s.

Each provides a snapshot of life on Earth, while the Evolution Theater features an eight-minute film surveying the mammal family tree and the vast changes its members have been through in the past 225 million years.
