Gay selection

The essence of natural selection is to favor and conserve beneficial genetic variations and eliminate maladaptive ones. But how does it fit with Darwin's selection of evolution? Same-sex sexual behavior may seem to present a Darwinian paradox. It provides no obvious reproductive or survival benefit, and yet same-sex sexual behavior is fairly common — around % of individuals in diverse human societies — and is clearly influenced by genes.

Therefore, the theory goes, a low "dose" of these alleles enhances the carrier's chances of reproductive success. For example, an allele which makes the bearer attracted to men has an obvious reproductive advantage to women. It mocks those who "think it's a decision, and you can be cured with some treatment and religion - man-made rewiring of a predisposition".

On February 15, Muhsin Hendricks, an openly gay imam, Islamic scholar gay LGBT rights activist was shot and killed in Gqeberha, South Africa as he was leaving to. Hungary deepened its repression of lesbian, gay, bisexual, and transgender (LGBT) people on March 18 as the parliament passed a draconian law that will outlaw Pride.

The evolution of lesbianism is relatively understudied - it may work in a similar way or be completely different. Gay men have eighty percent fewer offspring than do heterosexual males, so this trait would be expected to undergo extinction within several generations.

The findings may help solve the puzzle of why, if homosexuality is hereditary, it hasn't already disappeared from the gene pool, since gay people are less likely to reproduce than heterosexuals. Same-sex sexual behavior may seem to present a Darwinian paradox. A minority of gay people disagree, maintaining that sexuality is a social constructexternaland they have made a conscious, proud choiceexternal to take same-sex partners.

Since the early s, researchers have shown that homosexuality is more common in brothers and relatives on the same maternal line, and a genetic factor is taken to be the selection. Male homosexuality, a trait that, at least among exclusive homosexuals, means people have no interest at all in the act of reproduction, should never have existed in the first place.

The allele - or group of genes - that sometimes codes for homosexual orientation may at other times have a strong reproductive benefit. Let's make each other laugh until it hurts Yale biologist Richard Prum argues that sexual selection is too often overlooked as a major driving force of evolution, including the emergence of same-sex behavior in humans.

Another way a "gay allele" might be able to compensate for a reproductive deficit is by having the converse effect in the opposite sex. If it appears in a man's genetic code it will code for same-sex attraction, but so long as this happens rarely the allele still has a net evolutionary benefit.

Also relevant - although in no way proof - is research identifying physical differences in the brains of adult straight and gay people, and a dizzying array of homosexual behaviour in animals. Within hours of returning to power Monday, United States President Donald Trump issued a stunningly broad executive order that seeks to dismantle crucial protections for.

Every now and then a family member receives a larger dose that affects his or her sexual orientation, but the allele still has an overall reproductive advantage. Spread the love Yale biologist Richard Prum argues that sexual selection is too often overlooked as a major driving force of evolution, including the emergence of same-sex behavior in humans.

There is some evidence for this second theory. What's your favorite dimension This would compensate for gay people's selection gay reproduction and ensure the continuation of the trait, as non-gay carriers of the gene pass it down. It provides no obvious reproductive or survival benefit, and yet same-sex sexual behavior is fairly common — around % of individuals in diverse human societies — and is clearly influenced by genes.

It's becoming scientific orthodoxy. The essence of natural selection is to favor and conserve beneficial genetic variations and eliminate maladaptive ones. One possibility is that the allele confers a psychological trait that makes straight men more attractive to women, or straight women more attractive to men.

Since gay people are less likely to reproduce than heterosexuals, many experts have wondered why, if homosexuality is caused by genetic factors, it wouldn't have been eliminated from the gene pool. But since gay and lesbian people have fewer children than straight people, a problem arises.

You look like someone I'd write angsty texts to at 2am In the last two decades, dozens of scientific papers have been published on the biological origins of homosexuality - another announcement was made last week. Human Rights Watch works for lesbian, gay, bisexual, and transgender peoples' rights, and with activists representing a multiplicity of identities and issues.

These observations raise the. During its Universal Periodic Review cycle, the United States of America (U.S.) received recommendations from Iceland, Belgium, France, and Malta regarding gay. There are two or more ways this might happen. Gay men have eighty percent fewer offspring than do heterosexual males, so this trait would be expected to undergo extinction within several generations.

And yet it does. Scientists don't know the answer to this Darwinian puzzle, but there are several theories. But scientific opinion is with Macklemore. It's possible that different mechanisms may be at work in different people. Macklemore and Ryan Lewis's hit song Same Love, which has become an unofficial anthem of the pro-gay marriage campaign in the US, reflects how many gay people feel about their sexuality.

How? To answer that question, researchers have gone to a place where homosexuality itself does not exist, at least in the form we know it: Samoa. Most of the theories relate to research on male homosexuality.
