                  Lamarck's Impact

                  So, how could these "favourable variations" occur?
              Darwin tried to answer this question from the standpoint of

              the primitive understanding of science in his age. According
              to the French biologist Lamarck, who lived before Darwin,
              living creatures passed on the traits they acquired during
              their lifetime to the next generation and these traits,
              accumulating from one generation to another, caused new
              species to be formed. For instance, according to Lamarck,
              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, and in his book The
              Origin of Species, for instance, said that some bears going into
              water to find food transformed themselves into whales over
              time. 24
                  However, the laws of inheritance discovered by Mendel
              and verified by the science of genetics that flourished in the
              20th century, utterly demolished the legend that acquired

              traits were passed on to subsequent generations. Thus,
              natural selection fell out of favour as an evolutionary
              mechanism.


                  Neo-Darwinism and Mutations

                  In order to find a solution, Darwinists advanced the
              "Modern Synthetic Theory", or as it is more commonly
              known, Neo-Darwinism, at the end of the 1930's. Neo-
              Darwinism added mutations, which are distortions formed
              in the genes of living beings because of external factors such
