Evolution is "an unpredictable and natural process of temporal descent with genetic modification that is affected by natural selection, chance, historical contingencies and changing environments." Natural selection is defined as being the primary mechanism driving evolutionary change. It is caused by variations which exist within a species due to differences in the genetic makeup of its individual members. This causes some individuals to be more likely to thrive in a given environment, and to produce offspring like themselves. Punctuated equilibrium is the concept that evolution did not happen at a steady rate. Rather, the historical record shows long periods of relative stability, such as the rpesent time, when few new species evolved. These periods were broken by short periods of rapid change. Now where do teachers draw the line? How much is scientific without being religious? How does one know?
