Sheep were among the first animals to be domesticated

Sheep were among the first animals to be domesticated, and they are raised all over the world. Wild sheep also live throughout the world — in the Middle East, Asia, Central Europe and North America — mostly in mountainous areas. Bighorn sheep live in the Rocky Mountain region of North America. Desert bighorn sheep live in Death Valley, California, as well as Nevada, Texas and northern Mexico. They can live on desert mountains as high as 4,000 feet (1,200 m). Urials can live even higher up. They are found in Asia and the Middle East on grassy terrains with elevations of up to 19,690 feet (6,000 m), according to the ADW.
