From my prior knowledge, all birds evolved from a specific lineage of dinosaur, I think it was the raptor? The raptor grew a beak, wings and feathers and over a billion years or 100 million whatever, bada bing bada boom, birds.
So I guess this means the chicken is the most ancient type of bird? If t-rex and the chicken have the closest DNA out of all the living birds, it must mean chickens are one of the oldest bird species. Whoda thunk.
