The theory of natural selection is known to affect human and animal behavior

The theory of natural selection is known to affect human and animal behavior. The theory affects the social and spiritual behaviors of individuals who study it (Brem and Ranney 2003). This knowledge acts as a deterrent to cohesion of human races and a threat to spiritual freedom. An individual from a race regarded as a minor would feel threatened by the existence of other major races. The theory is against the creation and the existence of sins. Actions that individuals refer to as sins according to the theory are just a way of eliminating the individuals who are not fit. Many people live pure lives because they expect to be rewarded after their struggle here on earth. The theory may make individuals lack a reason for struggling if there is no reward and god does not exist.
