Homosexuality : Genetic Or A Choice?

Many scientists have a difficult time understanding homosexuality on the evolutionary aspect. They believe a human beings’ main purpose is reproduction, which makes the sexual relationship between two males a confusing concept for most evolutionary thinkers (McKnight 1). Evolutionary thinkers believe that the less desirable genes are removed from the system when they are not breed as often, but this cannot be said for homosexual males who have been a continuing presence in most societies over numerous generations (McKnight 1). These evolutionary thinkers, like most humans, have a need to place others into

The studies conducted used a wide array of individuals, brother-sister, brother-brother and twins. Throughout the article, majority of the focus caters to homosexual men in relation and comparison to

A highly debated issue concerning homosexuality is whether sexual-orientation is biologically determined or if it is a socially learned behavior. One case study done about this topic gathered that “the homosexual desire seems in most cases to be implanted in those who develop an unusually strong attachment for one parent” (Cory 1951:67). This seems to suggest that homosexuality can be influenced by family structure or other sociological elements. On the other side of this argument, there is the belief that people are born either gay or straight. Even though there is no scientific or genetic evidence to prove this, there have been many studies done and most homosexuals interviewed take this view-point. McIntosh states, “[homosexuality] is still commonly seen as a condition characterizing certain persons in the way that birthplace or deformity might characterize them” (1968:182). To support their cause and to fight for acceptance in society, it would be beneficial to convince people that sexual orientation is biologically determined. “Research indicates that people who believe that homosexuality is a choice are more likely to condemn it than are those who believe gays and lesbians are born that way”

Why some people are attracted to members of their own sex whereas others are attracted to members of the opposite sex is no known cause or reason. There is belief to it possible contributing from genetics, hormonal and the environmental influences. One study stated that there is a 50 percent chance that if one identical twin is homosexual or bisexual, the other twin is too. Similar findings lead that some researchers estimate that sexual orientation is 30 to 70 percent genetic (Mustanski, Chivers, & Bailey, 2002).

He contradicted the argument that homosexual behaviour is related to genetic, hormonal or biological disorder. To abolish these views, the author mentions that ‘no school of medicine, medical journal or professional organization has ever recognized such claims (p. 2) - at least at the time he wrote the article in 1994.

It is a fair assumption to say that America is approaching a new age in understanding and accepting the many variations of human sexual orientation. More same-sex couples have fostered children than ever before in our nation 's history. Institutions such as military and professional sports have (slowly but surely) began to accept openly gay members. Most importantly, a recent amendment to the Marriage Act of 1961 now defines marriage as a union of two people; an amendment which removed the prohibition of same-sex marriages. These landmarks in the progression of social awareness surrounding sexual orientation are derivative of scientific findings disputing the "choice" theory. As outlined in Simon LeVay 's book, Gay, Straight, and the Reason Why, the result of someone 's sexual orientation "emerges from the prenatal sexual differentiation of the brain" (LeVay 2011: 271) What LeVay means in this context is, "whether a person ends up gay or straight depends in large part on how this process of biological differentiation goes forward, with the lead actors being genes, sex hormones, and the brain systems" (LeVay 2011: 271). Much research, proven and theoretical, has been done on the concept of what makes people gay. Many factors surrounding socialization in regards to sexual orientation have undergone extensive scientific scrutiny (LeVay 2011: 77). Although there is evidence that suggests social and environmental elements play a role in sexual orientation, it is

In one article by Marcia Malory, “Homosexuality & Choice: Are Gay People ‘Born This Way’”, she goes into multiple studies on the genetics of a gay child's parents. A study conducted in 1993 the “gay gene” matter arose when it was looked into the homosexual children's parents having a different X chromosome marker. Nonetheless genes do not control our behavior completely as does environment. The brain may also play a role in sexual preference, like the study in 1991 showing the difference in neurons and pituitary glands. Later in the 2000s more studies showed that gay men have more symmetrical hemisphere and amygdala resembles that of women's. The brain develops in the womb and continues through late adulthood. When did a fetus choose its

Sexual orientation refers to the emotional, sexual, and romantic attraction to men, women, or both genders. It also refers to a person’s sense of identity based on those attractions. In the early years, to be labeled as a gay, lesbian, or bisexual was known to be a mental illness. In recent years, it has been determined that it is a normal aspect of sexuality. Determining how one has this specific trait is up in the air. With homosexuality growing, sexual orientation has been a major discussion in the world throughout the last decade. Some have argued that it has to do with genetics, and some say that it has to do with the environment. This is known as the long-term controversy of nature versus nurture. The controversy discusses which side of the argument affects our behavior, intelligence, development, and personality. Scientists have been investigating and experimenting to find the answer to this debate. There has not been evidence that says one side is 100% the answer.

As time went on, homosexuality came to be accepted as more mainstream. To confirm an article entitled “Most say homosexuality should be accepted by society” reveals that among the findings from the latest Pew Research Center political typology survey, released May 4, 2011. The survey conducted ,stated that while the public is divided over same-sex marriage, a majority of Americans (58%) say that homosexuality should be accepted, rather than discouraged, by society. Among younger people in particular, there is broad support for societal acceptance of homosexuality. More than six-in-ten (63%) of

Sexual orientation is something that people hear about daily in the news, media, and daily lives of others, especially when it comes to the field of psychology and the nature versus nurture debate. For being as commonly debated and discussed as it is, there are many questions that come along with it: what is sexual orientation, how do people know their sexual orientation, what causes homosexuality, is it normal, is it possible to change, and can wanting LGBT, lesbian, gay, bisexual, and transgender, youth to change lead to suicide?

Other studies conducted suggest that homosexuality might be base on difference in the brain structure of homosexual and heterosexual males. In 1991, Simon LeVay, a researcher at salks institute for biological studies in San Diego, found that an area of the brain called INAH-3 was larger in heterosexual men as in homosexual men [6]. INAH-3 is a small cell cluster in the hypothalamus that is involve regulating male sex behavior. LeVay’s finding provided clues that prove that sexual attraction to some extent might be biological. Other studies following levay’s study suggest that homosexuality might be base on genetic. It is believe that “gay gene” is passed from mother tho son.

Science is uncovered origins a lot of things over the centuries and the human created much great inventions and even explored the surface of the moon; however, one question still on everyone’s mind and science may have solved one of greatest mysteries yet which is: how did homosexuality and heterosexuality evolve? Many psychologist, biologist and scientist may agree with sexual orientation is output from a combination of biological, hormonal, environmental and emotional factors and those many factors that influence to a development of human sexual orientation. However, being homosexual or bisexual is not mentally ill or abnormal in certain ways, although sexual minority is part of social problems that makes output from misinformation or prejudicial attitude. Diversity in sexual orientation has been a subject that has been seen in different perspectives by the different people (LeVay, 2010). Today there are the homosexuals, heterosexuals and bisexuals orientated people are forming a part of our society. This paper conduct an overall study of important and strong factors and provides accurate information and explanation for those who want to better understand development of sexual orientation.

what ever decision has been made, it has been done so on the basis of

The survey also shows that Americans remain deeply divided over the essential cause and nature of homosexuality. A 42% plurality believes that being a homosexual "is just the way that some people prefer to live," no change from a Los Angeles Times survey conducted in 1985. But there has been a rise in the percentage who say homosexuality is "something that people are born with" ­ from 20% in the Times survey to 30% currently. The public also is split on the question of whether a gay person 's sexual orientation can be changed ­ 42% say it can, the same number disagrees.

The question of what causes some people to be sexually attracted to members of their own gender generates many different answers. In recent years, startling new research (Barinaga, 1993, p.17) has indicated that homosexuality is possibly inherited and determined by biological differences in Brain structure and genes. This study raises an interesting question: If homosexuality is hereditary, is there any basis for societal discrimination against something innate? If it is nature, it is good. If it is good, it should be accepted. A genetic component in sexual orientation would send a message to homosexuals and the society that homosexuality is not a fault, and not the fault of anyone other than nature. Gays and lesbians are born in nature, just like some people who are inherited left-handed gene from their parents.
