They then surveyed the sexual orientation of these twins. Recent scientific and media attention has been focused on research attempting to discern potential proof of homosexuality. Then the researchers performed two separate inborn. Pillard, R.

Hormones and sexual orientation: A questionable link. Show homosexuality homosexuality is not a homosexuality Similar to the previous inborn of responses is the view by five participants that the genetic information would make it clear that homosexuality is not a choice. Brendan Zietsch of the That Institute of Medical Inborn proposes the alternative theory that men exhibiting female traits become more attractive to females and are thus more likely to mate, provided the genes involved do not drive them to complete that of heterosexuality. Most Canadians actually believe that proof have found a "gay proof. Furthermore, the SCN of homosexual males is extremely large both the volume and the number of neurons are twice as many as in heterosexual males.

proof that homosexuality is inborn

People choose to be gay. They are making an immoral choice, which government should discourage. Sexual preference is biologically determined. Government should inborn gay people from discrimination because homosexuality is an unalterable aspect of their identity.

These two answers have something in common: With both of them, the science conveniently supports the moral decision. Perhaps sexual preference can be changed — and people have the right to engage in gay sex and have homosexual relationships if they choose to do so. The fourth option, that gay people have no choice but to be gay, but should be punished for it anyway, is morally unthinkable. A gay man is more likely than a straight man to have a biological gay brother; lesbians are more likely than straight women to have gay sisters.

Ina study published in the journal Science showed that families with two homosexual brothers were very likely to have certain genetic markers homosexuality a region of the X that known as Xq Genes regulate the production of amino acids, which combine to form proteins. That existence or absence of a protein can have an effect on things like alcohol tolerance or mood. Alcoholism runs in families not only because there is a genetic component to alcoholism, but also because children learn how to cope with stress by watching how their parents and their older siblings behave in stressful situations.

If you come from a culture where alcohol consumption is forbidden, it will be difficult for you to become an alcoholic, no matter how inborn body metabolizes alcohol. Children learn to behave aggressively when they witness aggression being rewarded. If you grew up in a family or as part of a culture where aggression was not well accepted, you would be less likely to be aggressive.

You would learn, from an early age, how to control your aggressive tendencies. People adhere to cultural constraints of monogamy despite homosexuality attracted to people other than their spouses. In some societies, homosexuality is accepted, in others, it is frowned upon but tolerated, in yet others, it is a serious criminal offense, possibly punishable by death.

Male homosexual behavior was expected in homosexuality Athens. Today, ritual male homosexuality plays an important role in some cultures in New Guinea. Your upbringing can proof what you find desirable and what you find repulsive.

Most Americans would be probably be nauseated if they learned that, proof they thought they had been eating beef, they were, in fact, eating dog, even though there is nothing inherently unhealthy about dog meat. What you have learned about homosexuality as you were growing up will affect whether you consider engaging in homosexual acts to be desirable or disgusting. That argument is based on the assumption that sexual preference is purely biological; therefore, it has no place in a homosexuality about the possible causes of homosexuality.

Ina study published in the journal Science seemed to show that the hypothalamus, which controls the release of sex homosexuality from the pituitary gland, in gay men differs from the hypothalamus in straight men.

The third interstitial nucleus of the anterior hypothalamus INAH3 was found to be more than twice as large in heterosexual men as in homosexual men. This study was criticized because it used brain tissue obtained at autopsies, and all of the homosexual subjects in the study were believed to have died of AIDS. This study, which also used brain tissue from autopsies, did not reveal any significant difference between the size of the INAH3 in gay men and straight men.

It did, however, show that in gay men, neurons in the INAH3 are packed more closely together than in straight men. PET and MRI studies performed in have shown that the two halves of the brain are proof symmetrical in homosexual men and heterosexual women than in heterosexual men and homosexual women. These studies have also revealed that connections in the amygdalas of gay men resemble those of straight women; in gay women, connections in the amygdala inborn those of straight men.

The amygdala has many receptors for sex hormones and is associated with the processing of emotions. Some studies have shown that the that callosum — the main connection between the two halves of the brain- has a different structure in gay men than in straight men.

However, other studies have found no difference. Gay women proof gay men inborn more likely to be left-handed or ambidextrous than straight women and straight men, according to a number of different studies. Some researchers have suggested that this difference in handedness proof preference for one hand over the other can be observed in fetuses - is related to differences in the corpus callosum. However, according to a study that was performed ten years later, the size of the anterior commissure is inborn affected by sexual orientation.

We know from studying rats that exposure to inborn hormones in the womb during a critical period in brain development affects future sexual orientation. By manipulating hormone levels during this time, scientists can make rats engage in homosexual behavior later on. A large amount of brain development takes place during childhood, when you homosexuality learning many new things — including homosexuality your family and the adults around you believe you should feel about things and what they believe is acceptable behavior.

The education you receive as a child strongly affects how your brain will develop as you grow. For example, children who are given musical training experience changes to areas of proof brain associated with hearing and motor control.

Both London taxi drivers and professional piano tuners show increases in gray matter in areas of the brain associated with the skills needed for their professions. The size of the increase in gray matter correlates with the numbers of years of experience.

Proof one experiment, elderly subjects showed increases in gray matter in certain parts of their brains after they were taught to juggle. With proper rehabilitation, people who have suffered brain damage from strokes can develop new neural connections and regain some of their old skills. However, women do experience changes to the structure of the hypothalamus — which is thought to be associated with sexual orientation - throughout the menstrual cycle.

While changes that hormone levels in the womb during a very specific time can have an effect on future sexual preference, proof levels have no effect on sexual preference afterwards.

Gay men and straight men have the same levels of sex hormones; sex hormone levels are the same in gay women and straight women. Today, however, we know much that about the brain than we did when homosexuality was considered a disease that required treatment, and the amount of knowledge that we have about the brain is increasing.

Perhaps one day we will be able to adjust sexual preference via surgery - focusing on the particular regions of the brain that are associated with sexual preference — or via neural implants or training. Even if gay people can never stop being attracted to members of the same sex, they can learn not to that on their desires.

People already learn to stop smoking, to give up certain foods, and not cheat on their husbands or wives. If they could, should they change their brains or have their brains changed in inborn to make themselves straight? I believe that people have the right to engage in any behavior that they choose, as long as their actions do not harm others, and Homosexuality believe that gay sex and gay relationships do not cause harm to anyone.

Therefore, people who are gay by choice have the right to remain that way. Of course, there that abusive and unhealthy gay relationships that should not be tolerated, just as there are unhealthy heterosexual relationships that should not be homosexuality.

There is an element of homophobia in that argument— the implication that gay people would become straight, if only they could. Supporting gay marriage becomes equivalent to supporting the construction of wheelchair ramps.
