Australian researchers have examined mitochondrial DNA preserved in chicken bones from archaeological sites in Europe, Thailand, the Pacific, Chile, the Dominican Republic, and Spanish colonial sites in Florida, and determined that they all shared an ancient ancestor. “All of our domestic chickens are descended from a few hens that I like to think of as the ‘great, great grandmothers’ of the chicken world,” said Alison Storey of the University of New England. Chickens were domesticated at least 5,400 years ago, somewhere in Southeast Asia, and because chickens do not fly or swim, they would have had to migrate with people.
