The Red Junglefowl (Gallus gallus) is a tropical member of the phasianidae family. It is thought to be ancestral to the domestic chicken, with some hybridzation with the Grey Junglefowl. The Red Junglefowl was first domesticated at least five thousand years ago in Asia, then taken around the world, and the domestic form is kept globally as a very productive food source of both meat and eggs.
