Siebert 1 Evolution, Macro vs. Micro Blake Siebert Mr. Volkman Cultural Anthropology Siebert 2 There is a lot of debate about evolution. The Christians and other religions have many different feelings about evolution. Some say that evolution is not real at all and some agree with some of evolution. There are two main kinds of evolution. The first is macro evolution; this is the type that has the most disagreement. The second is micro evolution; this is the type that religions have a better time agreeing with. This paper will attempt to define the two and compare them. Evolution is change over time. Under this broad definition, evolution can refer to a variety of changes that occur over time—the uplifting of mountains, the erosion of riverbeds, or the creation of new species. The term biological evolution is a more specific type of evolution. Biological evolution refers to the changes over time that occurs in living organisms. Biological evolution is defined as descent with modification. Biological evolution occurs at different scales. These include small-scale evolution and broad-scale evolution. Small-scale evolution, also referred to as microevolution, is the change in gene frequencies within a population of organism’s changes from one generation to the next. Broad-scale evolution, also referred to as macroevolution, refers to evolution at a grander scale. It focuses on the progression of species or entire clades from a common ancestor to descendent clades over the course of numerous generations. ( Klappenbach) There is one particular aspect of evolution that needs to be given specific attention: the somewhat artificial distinction between what is called “microevolution” and “macroevolution”, two terms often used by creationists in their attempts to critique evolution and evolutionary theory.
