Nature vs. Nurture Essay

Homointimateity, Addictions and IntelligenceThere have always been disputes on whether the decision to be homosexual or heterosexual was based on biological or purlieual factors. These disputes are know as the Nature vs. Nurture argument. The two sides argue over how sex is chosen within a someone. Based on reproductive organs, sex is easily determined at birth male or distaff. Gender, however is the sexual identity an sepa marke takes on. It is possible for sex and grammatical gender to be different.For an example of keep up children who were both born with an injured or damaged reproductive organ, males usually can be raised successfully as females. In order to understand which factor is the deciding factor of a individuals gender, both sides of the case must be fully evaluated. DNA studies which appear to prove that gender is a brokertic trait. Researchers have analyzed the makeup of the human brain of homosexuals and heterosexuals seeking a fraternity between gender and the brains physiology.They found when studying the part of the brain directly related to a persons sexual drive, that homosexuals had an enlarged hypothalamus, whereas heterosexuals had a normal one indicating a direct correlation between the brain and gender selections (AllPsych).In researching DNAs role in gender identity, some scientist have identified the gene that determines a persons sexual preference. Although there are mounting evidence of the existence of a gay gene, the opposition denies the existence (AllPsych). People in support of the Nurture argument asseverate that is an individual conscious or subconscious decision as to his or her gender identify. While many claim that people may control their sexual orientation, their brain, and not the other way around are in reality controlling them.A person DNA and brain physiology control sexual preference which may be associated in the amygdale of the limbic system (Pscyhsmart). When scientist castrated the rats, stopping t he creation of androgen, the male rats became submissive. When the androgen was given to the female rats, they began to display masculine behaviors. This experiment resulted in the male rat being submissive and allowing the female rat tomount the male, unlike the normal male rat that would mount the female when engaging in education ( Lippa 102).Similar to humans, if male do not have proper balance of hormones with his body, he may presentation feminine traits. These hormones are a biological aspect of gender that affects the decision to be homosexual or heterosexual. On the other hand, for the purpose of this discussion, addiction can take many forms, including not only snapper use disorders, but also pathologic gambling, bulimia, and a host of other disorders. Dependency, abuse, and addiction are employ relatively interchangeably however, there is ongoing debate within the field regarding the best terminology.Furthermore, differences in how these phenotypes are surrounded can have an impact on the results of gene discovery efforts. Genetic loci that have been consistently associated with various forms of substance addiction, as well as those that demonstrate relevance to pharmacologic treatment. While the temper vs. nurture debate has raged, is the contribution of interactions between genetics and environment. In reality, gene expression is environment bloodsucking and it impossible to obtain pure estimates of genetic vs. environmental contribution one could not exist without the other.The environment a child experiences is partly a consequence of the childs genes as well as external factors. To some extent a person seeks out and creates his or her environment. If she is of a mechanical bent grass she practices mechanical skills if a bookworm, she seeks out books. Thus genes may create an appetite rather than an aptitude. Remember that the elevated heritability of short-sightedness is accounted for not just by the heritability of a gene for short si ghtedness but by the heritability of literate person habits.Conversely, on the discussion of intelligence, there are three facts about the transmission of intelligence that virtually everyone seems to get into 1. Both heredity and environment contribute to intelligence. 2. Heredity and environment interact in various ways.3. passing poor as well as highly enriched environments can interfere with the realization of a persons intelligence, regardless of the persons heredity (Sternberg & Grigorenko, 1997, p.xi). Intelligence that appears to relate to ability to reason abstractly, to tick and to adapt. In closing, homosexuality, addictions and intelligence have reliablestatistical relationships with important social phenomena, but they are a limited tool for deciding what to make of any given individual. As stated by Ridley, bugger off Nature has plainly not entrusted our genetic capacities to the blind fate of a gene or genes she gave us parents, learning, language, culture and ed ucation to program ourselves with.WORKS CITEDJohnson, Ryan D.
