The Theory of Evolution
Charles Darwin's theory of evolution was based on natural selection as the engine of change in living beings. Later, with the advances in genetics, mutation was added to the theory as the source of the variations on which natural selection would act. The mutation-natural selection binomial thus became the main mechanism proposed for biological diversity. Do mutation and natural selection have the creative capacity assigned to them? Can they transform an organism into a different one by means of small changes accumulated over a long period of time? Are there other natural mechanisms that can do the job?
