		| Exactly when and where the chicken was domesticated remains  controversial. Genomic studies estimate that the chicken was  domesticated 8,000 years ago[45]  in Southeast Asia and spread to China and India 2,000 to 3,000 years  later. Archaeological evidence supports domestic chickens in Southeast  Asia well before 6000 BC, China by 6000 BC and India by 2000 BC.[45][52][53] |
