This is not a homework question, not a theory, not a debate about evolution v creation, don't turn into such, please. I'm just curious; is the chicken an animal that is evolving into a flighted bird, or a flighted bird that is evolving into a quad? OR are there some species of chickens going one way and others the other way? What will those wings be used for in the future? I'm not a biologist, so I am hoping there will be scholarly information. Mods, if Posters say things like 'twaddle' and 'chicken wings with beer could you just remove those Replies, instead of closing the Thread!? If the chickens were flighted birds, and that is only one possibility, as they could be evolving towards flighted animals, did they just get conditioned by apes who could keep them in toasty barns? Is this simple 'biology' that the great biologists and evolutionists have already explained? [Really - scientific and scholarly Replies or not at all - we shall see] It's either A. a completely analyzed and documented question or B. an interesting scientific curiosity.
