  • "Gallus gallus" redirects here. For other subspecies, see Chicken. The red junglefowl (Gallus gallus) is a tropical member of the family Phasianidae. It is the primary progenitor of the domestic chicken (though genetic evidence strongly suggests some past hybridisation with the grey junglefowl as well). The red junglefowl was first domesticated at least five thousand years ago in Asia. Since then it has spread around the world, and the domestic form is kept globally as a very productive food source of both meat and eggs.
  • The chicken (Gallus gallus) is an important model organism that bridges the evolutionary gap between mammals and other vertebrates and serves as the main laboratory model for the approx9,600 extant avian species. The chicken also represents the first agricultural animal to have its genome sequenced. Modern birds (Ornithurae) evolved from therapod dinosaurs9, 10 in the middle of the Mesozoic era. [1] [2].
