Natural Selection


According to the theory of evolution, living things came into existence by means of coincidences, and developed further as a consequence of coincidental effects. Approximately 3.8 billion years ago, when no living organisms existed on earth, the first simple single-celled organisms (prokaryotes) emerged. Over time, more complex cells (eukaryotes) and multicellular organisms came into being. In other words, according to Darwinism, the forces of nature built simple inanimate elements into highly complex and flawless designs.

In evaluating this claim, one should first consider whether such forces in fact exist in nature. More explicitly, are there really natural mechanisms which can accomplish evolution according to the Darwinian scenario?

The neo-Darwinist model, which we shall take as the mainstream theory of evolution today, argues that life has evolved through two natural mechanisms: natural selection and mutation. The theory basically asserts that natural selection and mutation are two complementary mechanisms. The origin of evolutionary modifications lies in random mutations that take place in the genetic structures of living things. The traits brought about by mutations are selected by the mechanism of natural selection, and by this means living things evolve. However, when we look further into this theory, we find that there is no such evolutionary mechanism. Neither natural selection nor mutations can cause different species to evolve into one another, and the claim that they can is completely unfounded.
