Mutation is a change that occurs in the DNA which can happen when there is a failure while the DNA is replicating or repairing itself, or when there is an exposure to radiation or other harmful chemicals. Mutations are random. A random change in a complex organism can only be either harmful or ineffectual, which implies that it cannot lead to transformation – to evolutionary development. During mutation, the genetic information is either being rearranged or destroyed; it does not add any information to the DNA, making it impossible to create a new organ or even new species. One mutation disaster was the 1986 Chernobyl tragedy in Ukraine. This happened when a reactor in the Chernobyl Power Plant exploded, which led to the suffering of animals and humans, not just in their generation but also to those that followed. In fact, the number of babies born with defects increased to 200%. Animal offsprings were also born with various defects due to mutation. How can such harmful mechanism result in a good one --- evolution, for …show more content…
“Irreducibly complex structures” means structures that “could not have possibly evolved from lesser structures.” This term was coined by Michael Behe, an American biochemist and the author of Darwin's Black Box. Systems of irreducible complexity are biological systems that cannot evolve through modifications or mutation. If random mutation could ever be able to generate the required genetic information to produce such complex systems, multiple immediate mutations would be needed. But this is the flaw. As explained by Behe, “If more than one [mutation] is needed, the probability of getting all the right ones grows exponentially worse.” The best example is the eye. An eye could not have been formed from a much lesser complex structure because every tiny part is necessary for it to function. Supposing that organisms once had no sight, and because of the mechanism called natural selection, in order for the organisms to survive, they developed eyes. But which could have evolved first? Sclera?? Iris? If we follow that the organisms have to develop something to be advantageous in the wild, then eyes should be formed perfectly with its parts intact, all at once. But in reality, the probability of a genetic mutation generating each of these parts at the same time within an organism is
