by John DavisonAbstract—All genetic alterations occur in a matter of seconds. Accordingly, there is no reason to assume that evolution has been a gradual process. On the contrary, the fossil record demonstrates that major changes took place over very short time intervals. All attempts to transform species through selection of point mutations have failed. Chromosome rearrangements characterize the differences that exist between ourselves and our primate relatives. Such differences could not conceivably occur gradually. I have proposed, with Leo Berg, that phylogeny (evolution) has involved the derepression of preformed information which was present from very early in evolutionary history. I also agree with Julian Huxley, Pierre Grasse and Robert Broom that macroevolution is no longer in progress. Homo sapiens is apparently the most recent mammal to have evolved, suggesting that there has been a plan, as proposed by Robert Broom. Such a teleological view of evolution can have profound consequences on the way in which man views his place in the universe.
