Homosexual behavior in animals refers to the documented evidence of homosexual, bisexual and transgender behavior in non-human animals. Such behaviors include sex, courtship, affection, pair bonding, and parenting. A 1999 review by researcher Bruce Bagemihl shows that homosexual behavior, has been observed in close to 1500 species, ranging from primates to gut worms, and is well documented for 500 of them.[2][3] Animal sexual behavior takes many different forms, even within the same species. The motivations for and implications of these behaviors have yet to be fully understood, since most species have yet to be fully studied.[4] According to Bagemihl, "the animal kingdom [does] it with much greater sexual diversity – including homosexual, bisexual and nonreproductive sex – than the scientific community and society at large have previously been willing to accept."[5] Current research indicates that various forms of same-sex sexual behavior are found througout the animal kingdom. [6] A new review made in 2009 of existing research showed that Same-sex behavior is a nearly universal phenomenon in the animal kingdom, common across species.[7] http://en.wikipedia.org/wiki/Homosexuality_in_animals Biology and sexual orientation is the subject of research into possible biological influences on the development of human sexual orientation. No simple cause for sexual orientation has been conclusively demonstrated, and there is no scientific consensus as to whether the contributing factors are primarily biological or environmental. Many think both play complex roles.[1][2] The American Academy of Pediatrics and the American Psychological Association have both stated that sexual orientation probably has multiple causes.[3][4] Research has identified several biological factors which may be related to the development of a heterosexual, homosexual, or bisexual orientation. These include genes, prenatal hormones, and brain structure. Conclusive proof of a biological cause of sexual orientation would have significant political and cultural implications.[5] http://en.wikipedia.org/wiki/Biology_and_sexual_orientation
Today, according to American Psychological Association: Psychologists, psychiatrists, and other mental health professionals agree that homosexuality is NOT an illness, a mental disorder, or an emotional problem. More than 35 years of objective, well-designed scientific research has shown that homosexuality, in and itself, is not associated with mental disorders or emotional or social problems. Homosexuality was once thought to be a mental illness because mental health professionals and society had biased information. In the past, the studies of gay, lesbian, and bisexual people involved only those in therapy, thus biasing the resulting conclusions. When researchers examined data about such people who were not in therapy, the idea that homosexuality was a mental illness was quickly found to be untrue. In 1973 the American Psychiatric Association confirmed the importance of the new, better-designed research and removed homosexuality from the official manual that lists mental and emotional disorders. Two years later, the American Psychological Association passed a resolution supporting this removal.[1][71][72] http://en.wikipedia.org/wiki/Homosexuality
