FIRST DOMESTICATION OF CHICKEN

About:

• The DNA sequencing of 863 genomes has showed the first domestication of chicken occurred in southwestern China, northern Thailand and Myanmar.
  
  
• The results contradicted the earlier claim that chickens were domesticated in northern China and the Indus Valley.
  
  
• The 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.
