NATURE Holy Cow

Discover how cows have altered human life, human biology, and the geography of the world. Thursday, May 27 at 8 p.m. on PBS-HD.

The humble, extraordinary and all-giving cow gets a closer look in this story of how we changed the cow and how in turn the cow changed us, forever.

About 8,000 years ago, the relationship between cows and man began with the revolutionary advent of domestication in Mesopotamia, the Indus River Valley, and Africa. There were many possible candidates for the job but only the cow fit the specific criteria humankind needed: not too flighty, breeds well in captivity, grows at a good pace, not aggressive, requires a low maintenance diet. Our ancestors chose wisely: Cows provide just about all of our basic needs, from milk and meat to muscle.
