Farming is believed to have originated around 10,000 years ago in East Africa and the Middle East by First Nations peoples at the end of the Ice Age, according to scientists. The first crops grown were likely wheat and barley, as their seeds are commonly found from that era. Dogs were possibly the first domesticated animals, kept as pets starting 13,000-30,000 years ago, while sheep, goats, cattle and pigs were domesticated for food around 9000-7000 BC.
