Homosexuality is romantic attraction, sexual attraction or sexual behavior between members of the same sex or gender. When it comes to homosexuality, for many people the recurring idea is that it’s something unnatural. But what does unnatural really mean? The definition of the term is something that goes against natural or human laws especially in relation to morality. Homosexuality is normal and is noticed form the ancient times. Between two and eleven percent of human adults report experiencing some homosexual feelings, though the figure varies widely depending on the survey. Homosexuality exists across cultures and even throughout the animal kingdom. Between six and ten percent of rams prefer to mount other rams, not ewes. Certain groups of female Japanese monkeys prefer the company of other females, American bison, polecats or elephants, both males and females have been observed courting and mating with others the same sex. In the case of giraffes, nine out of ten couplings occur between males. Bonobos form matriarchal societies, where 60% of sexual relations occur between females. In lions, 8% of mating observed are among males, and in the case of dogs, numerous research studies affirm the existence of patterns of homosexual behavior. As for birds, all species that form parental relationships do so, to a greater or lesser extent, with members of the same sex. As many as a quarter of black swans are homosexual. Penguins have even struck up same-sex relationships in zoos in different parts of the world. Studies have shown that up to 85% of lesbian pairs are found in populations of western seagulls. And they’re not the only ones. Pigeons, vultures, ibis, lizards, sheep, macaques, hyenas, flies, dragonflies and countless other animal species are challenging the notion that homosexuality is “unnatural”.
Sexual orientation is a very complex phenomenon. The exact cause of homosexuality is not know till now. But the reason can be understood from many scientific studies. In the case of a study of male twins, scheduled for presentation at the annual meeting of the American Society of Human Genetics (ASHG) in Baltimore, Maryland, today, could help explain that paradox. It finds that epigenetic effects, chemical modifications of the human genome that alter gene activity without changing the DNA sequence, may have a major influence on sexual orientation. The gay gene has some association with regions of Chromosome 8 and with the Xq28 gene on the X chromosome.
If Being Gay Is a Choice:-
If you ask most gay people, they will tell you that being gay is not something they chose to be. It makes sense, as one has to wonder why anyone would choose to be something that could cause them to be scorned by society, rejected by their families, denied rights, and subjected to possible violent hate crimes. Many gays and lesbians would argue that being gay is not a choice, but whether to act on it is. We don’t choose our sexual orientation, but we do choose whether or not to come out of the closet. Most scientific organizations also believe that homosexuality is not a choice and that biology plays some role. The National Mental Health Association says that most researchers believe sexual orientation is complex, and that biology plays an important role. In other words, many people are either born with their sexual orientation or establish it at an early age.
