Cattle and Aurochs

Humans turned wild cattle into cows, domesticating the animals about 8,000 years ago. Over time they bred cows for meat or milk production.

Cows have a digestive system with 4 chambers that allows grass they eat to ferment before it ultimately becomes cow fuel. The system sends grass back to the mouth for a good chew — an action called rumination.
