The NAS's Error in Portraying Molecular Biology as
                                    Evidence of Evolution

                 Supposedly, the ancient original myoglobin molecules slowly
                 evolved along two paths until the precisely designed a- and b-
                 haemoglobin molecules resulted that function only when linked to-
                 gether in groups of four to work in the blood in a much different
                 way under very different conditions from myoglobin in the muscle
                 cells. What we have today in modern myoglobin and haemoglobin
                 molecules are marvels of perfect designs for special, highly de-
                 manding tasks. Is there any evidence that intermediate, half-
                 evolved molecules could have served useful functions during this
                 imaginary evolutionary change process, or that any creature could
                 survive with them in its blood? There is no such information.
                 Modern vertebrates can tolerate very little variation in these mole-
                 cules. Thus, the supposed evolutionary history of the allegedly ho-
                 mologous globin molecules is a fantasy, not science. 1

                 As Dr. Kofahl makes clear, the NAS's claims regarding molecu-
            lar homology are not science at all, but merely fantasy, like all its
            other claims.
                 Moreover, the evolutionists' accounts fail to explain the origin of
            the myoglobin protein. They say that hemoglobin evolved from myo-

            globin, but how myoglobin came into existence is still a mystery
            to them.

                 It is suggested in Science and Creationism that an evolutionary
            family tree can be drawn up by comparing the proteins in living
            things, such as hemoglobin, myoglobin, or cytochrome c, and that
            this tree will agree with the paleontological and anatomical facts. This
            claim is set out in these terms:
