When some peopled are asked about the definition of evolution, they might say some jumble thoughts about Darwin’s theories and monkeys evolving into humans. That may be all they can say about it, but they know there’s more to evolution than that. This is probably all they can say with any authority about what they know. In secondary school, teachers will often awkwardly past over the subject without going into much depth; this maybe because of past controversies about the teaching of evolution in secondary school. But as college students, we now have the chance to learn from the stance of new Anthropologists a more clear definition and idea about the process of evolution. In this essay, we will be describing evolution through the four forces that drive the process. This will include the concepts of Natural Selection, Mutation, Gene Flow, and Genetic Drift. We will also discuss the other concepts of evolution that relate to these forces to create a better understanding. The process of evolution comes in two forms Microevolution and Macroevolution. Just as the term suggests, both takes place on a different scale in the process. Microevolution defined as “changes in allele frequencies in populations.” (Haviland, et al. 42) Populations are smaller groups of the same species that interbreed, and alleles are the genes that create a trait within populations. This means that this evolution takes place on a genetic level in small groups, while Macroevolution deals with formation of…
