ABSTRACT Research on the causes of human sexual orientation has been marshaled in support of predetermined and opposing theological viewpoints. Indeed, some recent studies have again proposed that genetic factors play an important role in its aetiology. Since then more and more research has revealed that same-sex sexual behavior is influenced by multiple genes and environmental factors. Furthermore, the etiology of homosexuality is often studied separately by social and biological scientists, rather than from an interdisciplinary perspective, which may provide additional insights into the The persistence of homosexuality in human populations, despite its apparent lack of direct reproductive benefits, has intrigued researchers for decades. This paper examines the interplay of A new cross-species study shows same-sex sexual behaviour has social benefits for groups, which explains its high frequency in humans and Homosexuality is often considered to be a “moral issue” in society, particularly in religious groups; whether it should be considered socially acceptable is an ongoing debate that has Homosexuality has been a constant throughout human evolution and civilization, and yet, science has been slow to look at the causes of sexual preferences. Studies on twins have established that homosexuality is more common in identical (monozygotic) A genome-wide association study of same-sex sexual behavior identifies loci associated with human sexual orientation. Associated research findings from the National Clues to evolution of homosexuality The genetic patterns associated with homosexual behaviour might help people who have only heterosexual sex There is no single “gay gene,” a new study found.
