WHY ARE PEOPLE GAY? GAY BY CHOICE OR IS BEG GAY GEIC?

It very much appears that same-sex sexual attractn is not a choice but actg on is; so if you fe gay as the mere prence of same-sex attractn, then om everythg we unrstand, beg gay is not a choice. If, on the other hand, you nsir someone to be gay only if they act on their same-sex attractn then beg gay n be nsired a choice pendg on an dividual's behavr.

” Many people, cludg sex rearchers and scientists, believe that sexual orientatn is like a sle wh entirely gay on one end and entirely straight on the other. Scientists may have fally solved the puzzle of what mak a person gay, and how is passed om parents to their children.A group of scientists suggted Tuday that homosexuals get that tra om their oppose-sex parents: A lbian will almost always get the tra om her father, while a gay man will get the tra om his mother.The heredary lk of homosexualy has long been tablished, but scientists knew was not a strictly geic lk, bee there are many pairs of intil tws who have differg sexuali.

Scientists om the Natnal Instute for Mathematil and Blogil Synthis say homosexualy seems to have an epigeic, not a geic lk.Long thought to have some sort of heredary lk, a group of scientists suggted Tuday that homosexualy is lked to epi-marks — extra layers of rmatn that ntrol how certa gen are exprsed. In homosexuals, the epi-marks aren't erased — they're passed om father-to-dghter or mother-to-son, explas William Rice, an evolutnary blogist at the Universy of California Santa Barbara and lead thor of the study."There is pellg evince that epi-marks ntribute to both the siary and dissiary of fay members, and n therefore feasibly ntribute to the observed faial herance of homosexualy and s low nrdance between [intil] tws," Rice not.Rice and his team created a mathematil mol that explas why homosexualy is passed through epi-marks, not geics.

WHAT DO THE BIBLE SAY ABOUT BEG BORN GAY?

Evolutnarily speakg, if homosexualy was solely a geic tra, scientists would expect the tra to eventually disappear bee homosexuals wouldn't be expected to reproduce.

But bee the epi-marks provi an evolutnary advantage for the parents of homosexuals: They protect fathers of homosexuals om unrexposure to ttosterone and mothers of homosexuals om overexposure to ttosterone while they are gtatn."The epi-marks protect fathers and mothers om excs or unrexposure to ttosterone — when they rry over to oppose-sex offsprg, n e the masculizatn of femal or the femizatn of mal," Rice says, which n lead to a child beg gay. Rice not that the markers are "highly variable" and that only strong epi-marks will rult a homosexual offsprg.Though scientists have long spected some sort of geic lk, Rice says studi attemptg to expla why people are gay have been few and far between."Most mastream blogists have shied away om studyg bee of the social stigma," he says. Well there are many exampl of homosexualy nature, 's very mon." Homosexual behavr has been observed black swans, pengus, sheep, and other animals, he says.Rice's mol still needs to be tted on real-life parent-offsprg pairs, but he says this epigeic lk mak more sense than any other explanatn, and that his team has mapped out a way for other scientists to tt their work."We've found a story that looks really good," he says.

Maybe we n agree that the image evoked by "born gay"—that ltle girl neonate appearg wearg overalls and graspg a toy tck—do not help thk through qutns of sexual sire and inty. Many homosexuals hold to the belief that they were born that way, and there are some rearchers who suggt, on the basis of several recent studi, that there may be a geic predisposn toward homosexualy some people.

In any se, other scientists have challenged the studi, and there is prently no generally accepted scientific evince that the homosexual clatn is born. Gay nrologist Simon LeVay explas that sexual orientatn is “the tra that predispos to experience sexual attractn” (Gay, Straight, and the Reason Why, 1).

CLIL STUDY CONFIRMS PEOPLE ARE NOT BLOGILLY “BORN GAY”

Humans have tried to unrstand human sexualy for centuri — and geics rearchers joed the ay the early 1990s after a seri of studi on tws suggted homosexualy ran fai. “As a teenager tryg to unrstand myself and unrstand my sexualy, I looked at the ter for “the gay gene” and obvly me across Xq28,” said Fah Sathirapongsasuti, a study -thor and senr scientist at 23andMe, which he joked once led him to believe he hered his gayns om his mother.

The rearchers had members of the same-sex muny review the study’s sign and language, and they adm that their termology and fns for gay, lbian and heterosexual do not reflect the full nature of the sexualy ntuum. “[Our study] unrsr an important role for the environment shapg human sexual behavr and perhaps most importantly there is no sgle gay gene but rather the ntributn of many small geic effects sttered across the genome,” Neale said. In 1996, The Advote, a gay and lbian magaze, asked rears what they believed the potential impact would be to the advancement of gay and lbian rights if a scientific disvery prov a blogil basis for homosexualy.

About 61 percent of the magaze’s rears asserted that such scientific rearch would advance the e of gays and lbians and lead to more posive attus toward homosexualy. To that end, gay activists and the liberal media have actively enuraged the ia that homosexualy is hered and unchangeable, and rearchers have diligently sought scientific evince to back up that claim. Unfortunately for the pro-homosexualy movement, the rearch on this subject has failed to tablish any scientific evince that shows a purely geic basis for homosexualy.

WHAT SCIENCE KNOWS ABOUT WHY PEOPLE ARE GAY

LeVay believed the differenc proved a blogil basis for homosexualy, but he failed to nsir a variety of reasons, other than geic, that the bras were different. His team of rearchers began a seri of gene lkage studi, which fai wh several homosexuals unrwent geic analysis to terme if any chromosomal variants uld be found the fay and if the variant rrelated wh those dividuals who displayed the homosexualy.

ARE SOME PEOPLE BORN GAY?

Evince om pennt rearch groups who studied tws shows that geic factors expla about 25-30% of the differenc between people sexual orientatn (heterosexual, gay, lbian, and bisexual). Three gene fdg studi showed that gay brothers share geic markers on the X chromosome; the most recent study also found shared markers on chromosome 8.

Gen uld themselv nudge one towards a particular sexual orientatn or gen may simply teract wh other environmental factors (such as sex hormon the womb environment) to fluence later sexual bras of gay and heterosexual people also appear to be anised differently.
