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.
