The Sri Lankan junglefowl (Gallus lafayettii sometimes spelled Gallus lafayetii), also known as the Ceylon junglefowl or Lafayette's junglefowl, is a member of the Galliformes bird order which is endemic to Sri Lanka, where it is the national bird. It is closely related to the red junglefowl (G. gallus), the wild junglefowl from which the chicken was domesticated. However, a whole-genome molecular study rather show that Sri Lankan junglefowl and grey junglefowl are genetically sister species than with the red junglefowl.[2] Sri Lankan junglefowl and red junglefowl diverged about 2.8 million years ago, whereas time of divergence between the Sri Lankan junglefowl and grey junglefowl was 1.8 million years ago.[2]
