These clips from the NATURE episode, "Moments of Impact: Hunters and Herders," can be used in the classroom to explore the various attributes of different predators on the African grasslands.

Clips from the NATURE episode "Holy Cow!" show the cow's digestive system and illustrate other naturally evolved and artificially selected traits of cattle.
