Numbering a little over one billion, domestic sheep are also the most numerous species of sheep . An adult female sheep is referred to as a ewe (/ juː /), an intact male as a ram or occasionally a tup, a castrated male as a wether, and a younger sheep as a lamb . </P> <P> Sheep are most likely descended from the wild mouflon of Europe and Asia . One of the earliest animals to be domesticated for agricultural purposes, sheep are raised for fleece, meat (lamb, hogget or mutton) and milk . A sheep's wool is the most widely used animal fiber, and is usually harvested by shearing . Ovine meat is called lamb when from younger animals and mutton when from older ones . Sheep continue to be important for wool and meat today, and are also occasionally raised for pelts, as dairy animals, or as model organisms for science . </P>
