Coyne offers evidence for evolutions side against creationists that wing development would be a disadvantage rather than an advantage. He states that process would be simple, from the gliding step to the flapping of such wings to be able to fly. He offers proof in the form of the Archaeopteryx, which possesses large feathers and an opposable toe. Why would the development of feathers appear; Coyne says for insulation likely but wouldn't fur act as an equally efficient insulator and also not get in the way rather than large feathers, which would also create wind resistance to slow down the Archeopteryx from running? Also, it is necessary to have enough feathers in proportion to body weight to even glide an effective distance to escape from predators. Is it a possibility that such feather mass appeared simply through evolution for insulation? Offer evidence which provides for a stronger argument for evolution of birds and refute the claims made above.
