The Rocky Mountain goat and the chamois are not true goats but are closely related.
Goats are hardy cliff dwellers, preferring an arid climate.
They live in herds and feed on grass, weeds, shrubs, and other vegetation. Domestic goats, varieties of Capra hircus, are found throughout the world, most abundantly in Asia. They are raised for milk, flesh, hair and wool, skins, and, in certain areas, to control scrub growth. Goat's milk is easily digested and has greater protein and fat content than that of cows. Many dairy goats are hornless.
