The multiple-origin hypothesis of domestic chickens postulates different junglefowl species that were involved in the origin of domestic chickens.

Those observations suggested a possible contribution of the four junglefowls to the origin of domestic chickens and favored the multiple-origin hypothesis.

Although red and green junglefowls can still hybridize with chickens and the genome of one species is actually transferred over the species boundary, these observations are not direct evidence for the multiple-origin hypothesis of domestic chickens.
