Sheep were among the first animals to be domesticated by humankind (although the domestication of dogs probably took place 10 to 20 thousand years earlier); the domestication date is estimated to fall between 11,000 and 9000 BC in Mesopotamia and possibly around 7000 BC in Mehrgarh in the Indus Valley.To create man was a fine and original idea; but to add the sheep was a tautology.

- Sheep (Wikipedia)
Sheep or domestic sheep (Ovis aries) are domesticated, ruminant mammals typically kept as livestock. Although the term sheep can apply to other species in the genus Ovis, in everyday usage it almost always refers to domesticated sheep. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female is referred to as a ewe (/juː/), an intact male as a ram, occasionally a tup, a castrated male as a wether, and a young sheep as a lamb.
