The Errors of the American National Academy of Sciences



                 plex one with more features is to believe in the impossible. In
                 order to prove the evolutionist claims, every transitional stage be-
                 tween myoglobin and hemoglobin needs to be functional (and
                 more advantageous than the preceding stage), and that is impossi-
                 ble.

                      The American chemist Dr. Robert Kofahl, a critic of the theory
                 of evolution, makes the following comment on the impossibility of
                 the claim that hemoglobin evolved from myoglobin:
                      A good example of alleged molecular homology is afforded by
                      the a- and b- haemoglobin molecules of land vertebrates, includ-
                            ing man. These supposedly are homologous with an an-
                                                cestral myoglobin molecule similar
                                                           to human myoglobin.
