The first farming occurred around 10,000 years ago in areas like China, the fertile crescents of India, Egypt, and Western Asia. The earliest crops grown were wheat, barley, and peas, though the specific crops depended on location. Squash was also grown around this time. The first domesticated animals were dogs, which were used for hunting and protection of human tribes. Dogs evolved from wolves and today there are over 200 purebred dog species.
