The chicken (Gallus gallus domesticus) is a large and round short-winged bird, domesticated from the red junglefowl of Southeast Asia around 8,000 years ago. Most chickens are raised for food, providing meat and eggs; others are kept as pets [1] or for cockfighting.
Chickens were created when red junglefowl were domesticated for human use around 8,000 years ago [2] as subspecies Gallus gallus domesticus. They are now a major source of food for humans. However, undomesticated red junglefowl still represent an important source of meat and eggs in their endemic range.
Chickens were one of the domesticated animals carried with the sea-borne Austronesian migrations into Taiwan, Island Southeast Asia, Island Melanesia, Madagascar, and the Pacific Islands; starting from around 3500 to 2500 BC. [25] [26] By 2000 BC, chickens seem to have reached the Indus Valley and 250 years later, they arrived in Egypt. They ...

Among birds, the chicken was first domesticated in East Asia, seemingly for cockfighting, some 7,000 years ago. The horse came under domestication around 5,500 years ago in central Asia as a working animal. Among invertebrates, the silkworm and the western honey bee were domesticated over 5,000 years ago for silk and honey, respectively.
A number of factors determine how quickly any changes may occur in a species, but there is not always a desire to improve a species from its wild form. Domestication is a gradual process, so there is no precise moment in the history of a given species when it can be considered to have become fully domesticated.
The chicken was most likely domesticated for its eggs (from jungle fowl native to tropical and subtropical Southeast Asia and Indian subcontinent) before 7500 BCE. Chickens were brought to Sumer and Egypt by 1500 BCE, and arrived in Greece around 800 BCE, where the quail had been the primary source of eggs. [4]
Dogs and sheep were among the first animals to be domesticated. The domestication of vertebrates is the mutual relationship between vertebrate animals, including birds and mammals, and the humans who influence their care and reproduction. [1] Charles Darwin recognized a small number of traits that made domesticated species different from their ...
