Natural Selection:

Natural Selection is how Evolutionary Psychologists determined world behaviors. The idea, natural selection, is one of several different mechanisms that cause evolutionary change in populations. As stated by the creator of Natural Selection, Charles Darwin, in his book The Origen of Species, some hereditary traits may advantageous for survival, and therefore, the next generation will receive these beneficial traits. Natural Selection states that nature dictates the traits that assist in survival. The reason natural selection occurs is because individuals within a population vary and are not always identical. Natural selection produces evolutionary change because it changes the genetic composition of populations.
