Sheep were most likely domesticated from the mouflon (Ovis orientalis orientalis),over 10,000 years ago. They are bred for their wool, meat, leather and milk. There are currently over 200 breeds of sheep that vary based on size, coat, and coloration, as well as other selectively bred qualities. Though sheep have been domesticated for many thousands of years, the pioneering process of selective breeding in agriculture was developed by Robert Bakewell in Britain in the 1700s. Bakewell revolutionized many agricultural practices regarding horses and cows, but was most known for his work in improving the size and wool quality of sheep.
