Nature vs. Nurture
There is a big controversy between whether inherited genes or the environment influences and affect our personality, development, behavior, intelligence and ability. This controversy is most often recognized as the nature verses nurture conflict. Some people believe that it is strictly genes that affect our ways of life, others believe that it is the environment that affects us, and some believe that both of these influence us. A wide variety of characteristics have been considered in such debates, including personality, sexual orientation, gender identity, political orientation, intelligence, and propensity for violence or criminality ( Wright,1998).
Human nature is the range of human behaviors that is believed to be innate rather than learned. There is much debate over which behaviors are innate and which are learned, and whether or not this division applies equally to all individuals. Although “nurture” may have historically referred mainly to the care given to children by their parents, any environmental(not genetic) factor also would count as “nurture” in a contemporary nature versus nurture debate, including one’s childhood friends, one’s early experiences with television, and one’s experience in the womb(Wright,1998). Indeed, a substantial source of environmental input to human nature may arise from external variations in prenatal development (Wright, 1998).
Tests are done often on identical twins that were separated to see how they are influenced. In the past twenty years, it has been discovered that there is a genetic component to about every human trait and behavior (pinker, 2002). Jim L. and Jim S. were first reunited at age 39. They were genetically identical twins, reared apart since infancy by different adoptive families in Ohio and unaware of each other’s existence. As children, each twin had had a dog named Toy. Each bit his fingernails and, since age 18, had suffered from mixed headache syndrome, a combined...
