EVER THOUGHT ABOUT THE TRUTH?


                Natural selection holds that those living things that are
             stronger and more suited to the natural conditions of their habitats
             will survive in the struggle for life. For example, in a deer herd
             under the threat of attack by wild animals, those that can run
             faster will survive. Therefore, the deer herd will be comprised of
             faster and stronger individuals. However, unquestionably, this
             mechanism will not cause deer to evolve and transform them-
             selves into another living species, for instance, horses.
                Therefore, the mechanism of natural selection has no evolu-
             tionary power. Darwin was also aware of this fact and had to
             state this in his book The Origin of Species:

                Natural selection can do nothing until favourable individual differ-
                ences or variations occur. 14



                Lamarck's Impact
                So, how could these "favorable variations" occur? Darwin tried
             to answer this question from the standpoint of the primitive un-
             derstanding of science at that time. According to the French biolo-
             gist Chevalier de Lamarck (1744-1829), who lived before Darwin,
             living creatures passed on the traits they acquired during their
             lifetime to the next generation. He asserted that these traits, which
             accumulated from one generation to another, caused new species
             to be formed. For instance, he claimed that giraffes evolved from
             antelopes; as they struggled to eat the leaves of high trees, their
             necks were extended from generation to generation.
                Darwin also gave similar examples. In his book The Origin of
             Species, for instance, he said that some bears going into water to
             find food transformed themselves into whales over time. 15
                However, the laws of inheritance discovered by Gregor Mendel
