Human social and genetic research seeks to understand the occurrence and magnitude of environmental (nurture) and genetic (nature) effects on people’s uniqueness, cognitive capacity, behavior, and interests. Adoption and twin research affirm that behavioral attributes are principally heritable (“In Colombia” par. 2). However, attempts to establish genes that influence behavior have generated minimal confirmed connections or relations. Behavioral genetics studies depict the significance of environmental aspects. In contrast with most behavioral scientists’ anticipations, pertinent environmental facets seem to be the ones that the twins reared together do not share. Studies of identical twins who have been raised in different regions fascinate not just researchers but also the public. Each pair of identical twins share 100% of their genetic characteristics (“In Colombia” par. 4). Research on identical twins who have been reared apart shows that half of their divergences in personality and pietism are genetically established. Additionally, the surrounding environment determines only about 25% of variations in attributes such as I.Q.
Psychologists have sought to clearly understand the impact of nurture and nature on human attributes for many decades. Following the scientific field’s realization that genes and environment have an essential role in human development, emphasis has shifted to the determination of the more influential one. Nurture many have an even more significant influence on human development and characteristics than originally alleged (“In Colombia” par. 9). In summary, anchored in numerous studies, it has been confirmed that a person’s behavior and traits are influenced by both nurture and nature. Although genetic disposition is essentially valuable in establishing human characteristics, there is always the necessity of an environmental prompt that makes the attribute to become visible in a person.
