WHY ARE THERE GAY MEN?
New rearch shows the gen that make men gay appear to make their mothers and nts more reproductively succsful. * why so many gay people *
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.
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. The term “homosexualy, ” while sometim nsired anachronistic the current era, is the most applible and easily translatable term to e when askg this qutn across societi and languag and has been ed other cross-natnal studi, cludg the World Valu Survey.
IS A LBIAN, GAY OR BISEXUAL INTY MORE COMMON TODAY?
The crease the number of visible gay and trans people is sometim treated as a cursy or a e for ncern by crics, but ’s not a surprise. It’s normal. * why so many gay people *
Dpe major chang laws and norms surroundg the issue of same-sex marriage and the rights of LGBT people around the world, public opn on the acceptance of homosexualy society remas sharply divid by untry, regn and enomic velopment.
As was 2013, when the qutn was last asked, attus on the acceptance of homosexualy are shaped by the untry which people live.
Those Wtern Europe and the Ameris are generally more acceptg of homosexualy than are those Eastern Europe, Rsia, Ukrae, the Middle East and sub-Saharan Ai. In many natns, there has been an creasg acceptance of homosexualy, cludg the Uned Stat, where 72% say should be accepted, pared wh jt 49% as recently as 2007. There also have been fairly large shifts acceptance of homosexualy over the past 17 years two very different plac: Mexi and Japan.
WHAT SCIENCE KNOWS ABOUT WHY PEOPLE ARE GAY
In many of the untri surveyed, there also are differenc on acceptance of homosexualy by age, tn, e and, some stanc, genr – and several s, the differenc are substantial.
For example, some untri, those who are affiliated wh a relig group tend to be ls acceptg of homosexualy than those who are unaffiliated (a group sometim referred to as relig “non”). In general, people wealthier and more veloped enomi are more acceptg of homosexualy than are those ls wealthy and veloped enomi. For example, Swen, the Netherlands and Germany, all of which have a per-pa gross domtic product over $50, 000, acceptance of homosexualy is among the hight measured across the 34 untri surveyed.
By ntrast, Nigeria, Kenya and Ukrae, where per-pa GDP is unr $10, 000, ls than two--ten say that homosexualy should be accepted by society. The study is a follow-up to a 2013 report that found many of the same patterns as seen today, although there has been an crease acceptance of homosexualy across many of the untri surveyed both years.
ARE MORY MEN MORE LIKELY TO BE GAY? WHY?
The 2019 survey shows that while majori 16 of the 34 untri surveyed say homosexualy should be accepted by society, global divis rema. Across the 34 untri surveyed, a median of 52% agree that homosexualy should be accepted wh 38% sayg that should be disuraged.
Central and Eastern Europeans, however, are more divid on the subject, wh a median of 46% who say homosexualy should be accepted and 44% sayg should not be. But sub-Saharan Ai, the Middle East, Rsia and Ukrae, few say that society should accept homosexualy; only South Ai (54%) and Israel (47%) do more than a quarter hold this view. Sce 1994, and there has been a relatively steady crease the share who say that homosexualy should be accepted by society sce 2000.
However, while took nearly 15 years for acceptance to rise 13 pots om 2000 to jt before the feral legalizatn of gay marriage June 2015, there was a near equal rise acceptance jt the four years sce legalizatn. More than eight--ten Democrats and Democratic-leang pennts (85%) say homosexualy should be accepted, but only 58% of Republins and Republin leaners say the same. In 22 of 34 untri surveyed, younger adults are signifintly more likely than their olr unterparts to say homosexualy should be accepted by society.
