Where do chickens come from?

Long ago, lots of wild chickens lived in India and East Asia (China, Thailand, Cambodia, and Vietnam). That’s where people first domesticated (tamed) chickens, maybe around 7000 BC.

Recent genetic evidence shows that people tamed chickens in two different places: in China and in India. Probably the people in each place didn’t know that the other ones were also taming chickens. By about 5000 BC, people in China were certainly keeping chickens, and by 3000 BC people in India and probably Vietnam also had domesticated chickens.
