Life’s Greatest Miracle

Evolutionary Perspective 

Every organism is said to have been undergoing evolution; human beings are not an exception. As they evolve, people go through the natural selection and adaptive behavior, and their psychology develops. Natural selection, according to biological studies, is a process by which an organism best suited to a particular environment survives (Santrock, 2015). Natural selection is based on the "survival of the fittest" slogan. Adaptive behavior is that which enables an organism to survive in a particular environment. For example, the adaptive response of an antelope in grassland to escape predators is to run away in case of danger. The running away of the antelope enables it to survive in its habitat. Psychologically, the need for culture amongst human beings increases as one older (Santrock, 2015). The increase in demand for culture implies that human beings identify with specific ways of life as they advance in age. This shows the evolutionary advancement in human beings as they progress age-wise (Santrock, 2015). 

Heredity-Environment Interaction 

There has been ongoing debate concerning the acquisition of behavior by the human beings. The primary source of the discussion is whether the acts are acquired naturally, or they are nurtured in the human beings. It is imperative to note that the environment plays an integral role in shaping behavior. Additionally, the interaction of human beings with others also models their way of thinking and perceiving life (Santrock, 2015). Arguably, some of the responses are innate while the others are acquired. The acquired behaviors manifest themselves more than the natural ones. For example, if a child is adopted, he or she is likely to behave the same way as the adoptive parents and less likely to have similar behavior with the biological parents. This is because the environment affects human behavior more than heredity. Twins raised in different backgrounds are expected to have different adaptive behaviors, with slight similarities in the hereditary characteristics.
