  • There are many theories about the domestication of chickens. They agree that the genomes of modern chickens, Gallus domesticus and the Asian junglefowl have many similarities. Therfore the junglefowl gallus gallus was the ancestor of now living chickings.
    Researchers have found fossils of early chickens dating back 8000 to 11,000 years ago in northern China and Pakistan. But genetics of living birds could not narrow the window for domestication. Reseach on chicken bones found on archaeological sides around the world made a lot clear.
    They found the oldest bones of likely chickens came from a site called Ban Non Wat in central Thailand, where farmers grew rice 3250 to 3650 years ago. Farmers buried many skeletons of young members of the genus Gallus as grave goods along with other domesticated animals-strong evidence that these birds were domesticated chickens, rather than wild jungle fowl.
