The theory of evolution by Darwin argues that all life in the world originates from a common ancestor (Charles and Joseph, 2003). This implies that all life is related since it has a common origin. Both plants and animals have a common ancestral origin. Over time, a simple organism undergoes evolution and develops into a very complex being (Charles 1997). There are many inferences and facts that are derived from the theory. The species in the world are fertile to reproduce. If all these species grew to reproduce, the population would grow rapidly. However, all the species do not survive to reproduce making the population remain roughly the same. Resources are limited but with time the supply stabilizes. All the living things that exist in the world struggle for survival. Every individual in the world is different from all other individuals. Individuals inherit some traits from their origin. In natural selection, only the fittest survive, and their traits are passed on to later generations. Those that are less suited do not survive or reproduce. They die and their traits are eliminated. Individuals in a given population adapt to the environment around them. The accumulation of these variations over time leads to the development of new species (Eldredge 2000). The theory has been rejected by many individuals who believe in creation. It was described as a theory that misleads and Darwin was described as a racist and a mass murderer. Adolf Hitler is thought to have employed the theory of natural selection as advocated for by Darwin during his tenure as the German leader.
