The existence of life on earth is driven by the forces of mutation, natural selection and speciation. Mutation is changes in gene structure causing changes in characteristics. Natural selection provides the mechanism by which mutations are selected for survivability and adaptation. Changes caused by mutation and natural selection lead to speciation, in which populations of creatures become seperated from each other.
A common misunderstanding about evolution and natural selection is that it's random because mutation is random, but that is incorrect[1]. Natural selection is anything, but random. However, neither is it directed. The idea that it is directed leads to the assumption that some species are more evolved than others. This is simply
