The second important point that negates Darwin’s theory is that both concepts put forward by the theory as “evolutionary mechanisms” were understood to have, in reality, no evolutionary power.
Darwin based his evolution allegation entirely on the mechanism of “natural selection”. The importance he placed on this mechanism was evident in the name of his book: The Origin of Species, By Means of Natural Selection…
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 themselves into another living species, for instance, horses.
Therefore, the mechanism of natural selection has no evolutionary 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 differences or variations occur. (Charles Darwin, The Origin of Species by Means of Natural Selection, The Modern Library, New York, p. 127)
