" "Evolutionary change is change in the genetic constitution of a population. This type of change can come about as a result of a number of factors. Immigration and emigration of organisms will bring new alleles and new allelic combinations into the population and will cause others to disappear. Mutation will lead to the formation of new alleles. The major claim of a Darwinian theory of evolution is that the principal factor of change is natural selection: The most important evolutionary changes come about because some allelic pairs are fitter than others, and these obtain greater representation for their constituents alleles in subsequent generations.

Additional quotes by Philip Kitcher
The Creationists are by no means the first to play on fears about what scientific inquiry will disclose. Anxieties about ourselves endure. If our proper study is indeed the study of humankind, then it has seemed—and still seems—to many that the study is dangerous. Perhaps we shall find out that we were not what we took ourselves to be. But if the historical development of science has indeed sometimes pricked our vanity, it has not plunged us into an abyss of immorality. Arguably, it has liberated us from misconceptions, and thereby aided us in our moral progress.
