Scientists believe that chickens evolved from the red jungle-fowl,  which, in turn, evolved from the more bird-like dinosaurs. Birds  seem to have originally been what is ca â¦ lled theropod dinosaurs,  in fact, and fossil evidence does show a relationship between birds  and these bird-like dinosaurs.hickens (Gallus domesticus) are known to be descendants of the famous Archaeopteryx from the Jurassic period.
Charles Darwin maintained that the domesticated chicken descended from the red jungle fowl, but new research from Uppsala University now shows that the wild origins of the chicken are more complicated than that. Yellow-skinned chickens have a different version of a gene than their white-skinned cousins. Darwin believed that all chickens came from a wild species known as the red junglefowl. When the researchers looked for the yellow-skin gene in the red junglefowl, they only found the genetic variant that codes for white skin.
