This is either due to the pressure of early hunter-gatherers' attempts to stabilise the food supply, which resulted in the existence of domesticated farm animals, or domestication of pets which are useful to humans.

The domestic chicken is descended primarily from the red junglefowl (Gallus gallus) and is scientifically classified as the same species.
