Impact on humans. The domestication of animals began with the wolf (Canis lupus) at least 15,000 years before present (YBP), which then led to a rapid shift in the evolution, ecology, and demography of both humans and numerous species of animals and plants.
The common features of today's sheep were already appearing in Mesopotamian and Babylonian art and books by 3000 B.C. Another indication of the early domestication is the fact that they are the only species of livestock unable to return to a feral orwild state.
