The domesticated chicken has a genealogy as complicated as the Tudors, stretching back 7,000 to 10,000 years and involving, according to recent research, at least two wild progenitors and possibly more than one event of initial domestication. The earliest fossil bones identified as possibly belonging to chickens appear in sites from northeastern China dating to around 5400 B.C., but the birds’ wild ancestors never lived in those cold, dry plains. So if they really are chicken bones, they must have come from somewhere else, most likely Southeast Asia. The chicken’s wild progenitor is the red junglefowl, Gallus gallus, according to a theory advanced by Charles Darwin and recently confirmed by DNA analysis. The bird’s resemblance to modern chickens is manifest in the male’s red wattles and comb, the spur he uses to fight and his cock-a-doodle-doo mating call. The dun-colored females brood eggs and cluck just like barnyard chickens. In its habitat, which stretches from northeastern India to the Philippines, G. gallus browses on the forest floor for insects, seeds and fruit, and flies up to nest in the trees at night. That’s about as much flying as it can manage, a trait that had obvious appeal to humans seeking to capture and raise it. This would later help endear the chicken to Africans, whose native guinea fowls had an annoying habit of flying off into the forest when the spirit moved them
