Darwin's Theory of Evolution is a slow gradual process. Darwin wrote, "…Natural selection acts only by taking advantage of slight successive variations; she can never take a great and sudden leap, but must advance by short and sure, though slow steps."

Evolution is the process by which populations of organisms change over generations. Genetic variations underlie these changes. Genetic variations can arise from gene variants (also called mutations) or from a normal process in which genetic material is rearranged as a cell is getting ready to divide (known as genetic recombination).

The first step in the process of creating stars is the formation of dense cores within a clump of gas and dust (Figure 21.8(a)).Describe the steps which led to the origin of life (organic molecules form, macromolecules polymerize, a hereditary mechanism develops, membrane-enclosed protocells form). Apply the principles of evolution by natural selection to pre-biotic scenarios. The origin of life is a mystery, the ultimate chicken-and-egg conundrum (R Service, 2015). Multicellularity has evolved at least 20 times since life first began, but no organisms have made the leap in the past 200 million years, so the process is difficult to study.
