            swered. There is no way to explain how the front arms of a reptile could
            have changed into perfectly functioning wings as a result of a distortion in
            its genes (mutation).
                 Moreover, just having wings is not sufficient for a land organism to
            fly. Land-dwelling organisms are devoid of many other structural mecha-
            nisms that birds use for flying. For example, the bones of birds are much
            lighter than those of land-dwelling organisms. Their lungs function in a
            very different way. They have a different muscular and skeletal system
            and a very specialised heart-circulatory system. These features are pre-req-
            uisites of flying needed at least as much as wings. All these mechanisms
            had to exist at the same time and altogether; they could not have formed




                              SPE CIAL LUNGS FOR BIRDS

            The anatomy of birds is very different from that of reptiles, their supposed ances-
            tors. Bird lungs function in a totally different way from those of land-dwelling ani-
            mals. Land-dwelling animals breathe in and out from the same air vessel. In birds,
            while the air enters into the lung from the front, it goes out from the back. Allah
            created this distinct system specially for birds, which need great amounts of oxy-
            gen during flight. It is impossible for such a structure to evolve from the reptile
            lung.
