These layers can then be separated on the ...Evolution - Natural Selection, Adaptation, Genetics: The central argument of Darwin's theory of evolution starts with the existence of hereditary variation.

Evolution as described by Charles Darwin in the nineteenth century is the result of random variations among individuals conferring different values of fitness in a given environment, therefore increasing or reducing the probability of transmitting these traits to their progeny.

It has three essential parts: It is possible for the DNA of an organism to occasionally change, or mutate. A mutation changes the DNA of an organism in a way that affects its offspring, either immediately or several generations down the line. The change brought about by a mutation is either beneficial, harmful or neutral.
