Goat

The domestic goat (Capra aegagrus hircus), along with sheep, were among the earliest domesticated animals. Goat remains have been found at archaeological sites in western Asia, such as Jericho, Choga, Mami, Djeitun and Cayonu, which allows domestication of the goats to be dated at between 6000 and 7000 B.C. Goats were kept for their milk and meat, along with uses being found for their dung, bone, hair, and sinew. Today there are several hundred breeds of goats, being breed specifically for meat, milk, fiber, and skin. Goats are often found in the Bible and the histories of other religions. A goat is a "clean" animal by Jewish law and was slaughtered for an honored guest. In the New Testament, Jesus told a parable of The Sheep and the Goats. Christianity has associated Satan with imagery of goats, based on the Greed deity Pan.
