Artificial Worms

Abstract

Natural selection works in the presence of chance or randomness. As random mutations take place, the form or function of organisms changes. With changes in the “appearance” of individual organisms may come an enhanced ability to survive and to pass on the respective traits to subsequent generations. However, because mutations continue to take place, and because the environment within which natural selection occurs is not constant, it is not automatic that the fitness of offspring increases from one generation to the next. The model of this chapter illustrates these workings of natural selection and randomness.
