Chickens were first domesticated in southwestern China

Study contradicts the earlier claim that they were reared in northern China and Indus Valley.

A recent study by scientists has revealed new details about the earliest domestication of chicken. The DNA sequencing of 863 genomes has showed the first domestication of chicken occurred in southwestern China, northern Thailand and Myanmar.

  • A collaborated study, which involved sequencing of genomes from all four species of the genus Gallus, five sub-species of Red Jungle Fowl and various domestic chicken breeds collected worldwide, revealed single domestication from Red Jungle Fowl sub-species Gallus gallus spadiceus.
  • The study also demonstrated that all five Red Jungle Fowl sub-species were genetically differentiated from each other approximately 50,000 years ago (much earlier than domestication), corresponding to their geographic ranges and taxonomic classifications.
  • The question of domestication of chickens has intrigued scientists for centuries. Charles Darwin postulated that chickens were domesticated around 4,000 B.C. from a single ancestor, Red Jungle Fowl in the Indus Valley. An important study published earlier from Uppsala University claimed the Grey Jungle Fowl had contributed to chicken domestication.
