Gallus gallus is a domesticated chicken-like bird (thus, the name “chicken”) that originates in southeast Asia. Ever since Darwin we've known that the chicken originated in southeast Asia, although the exact details of which one or more of several possible jungle fowls is the primal form has been debated.
Also asked, how long has the chicken been around?
So, it's more than likely that today's chicken has multiple ancestors. Chickens initially became domesticated between 8,000 and 10,000 years ago. There's also genetic evidence to suggest that there were simultaneous but independent domestication events in different parts of Asia and India.
When was the first chicken eaten?
Given the ubiquity of poultry on plates today, it may come as a surprised to learn that the first domesticated chicken was not for eating but for fighting. Humans raised fowl for cockfights starting in Southeast Asia and China as early as 10,000 years ago, but their meat wasn't enjoyed until later.
Where did the chicken evolve from?
In terms of RECENT evolution, all modern domesticated chickens are descendants of wild junglefowl (genus Gallus), which is native to tropical Asia.
