When a population of insects is sprayed with a deadly chemical like DDT, the most susceptible insects die but the insects most resistant to the poison survive to breed and leave offspring, which inherit the genes that provide resistance. After many generations of insects have been sprayed, the entire surviving population may be comprised of the DDT-resistant variety, and some new form of insect control will have to be applied. Such changes are not permanent, however, because the resistant mosquitoes are more fit than the others only for as long as the insecticide is applied. When the environment becomes free of the toxic chemical, the insect population tends to revert to what it was before. Almost all illustrations of “evolution in action” in textbooks or museum exhibits are similar to these examples. They involve no increase in complexity or appearance of new body parts or even permanent change of any kind. Small-scale, reversible population variations of this sort are usually called microevolution, although “adaptive variation” would be a better term. It is misleading to describe adaptive variation as “evolution,” because the latter term commonly refers also to macroevolution. Macroevolution is the grand story of how life supposedly evolved by purely natural processes from very simple beginnings to become complex, multicelled plants and animals, and eventually human beings, without God’s participation being needed at any step along the way. The primary flaw in the story of macroevolution is that all plants and animals are packed with information—the complicated instructions that coordinate the many processes enabling the body and brain to function. Even Richard Dawkins, the most famous living advocate of Darwin’s theory, admits that every cell in a human body contains more information than all the volumes of an encyclopedia, and every one of us has trillions of cells in his or her body, which have to work together in marvelous harmony. The greatest weakness of the theory of evolution is that science has not discovered a process that can create all the necessary information, which can be likened to the software that directs a computer. [b]This Darwinism mechanism has never been shown to be capable of creating new genetic information[/b] or new complex body parts such as wings, eyes, or brains. Without a mechanism that can be demonstrated to be capable of the necessary creation, the theory of evolution is just a fantasy with no real scientific basis.
