Gay sex and attraction may have evolved because individuals with a degree of same-sex attraction benefited from greater social mobility, integration and stronger same-sex social bonds. This may sound counterintuitive, given gay people are socially marginalised, ostracised and even criminalised in many societies. However, our argument addresses the early evolution of human sexuality, not how relatively recent phenomena like religion and religion-based legal structures have responded to sexual minorities.
Many studies since the pioneering research of Alfred Kinsey and colleagues have emphasised that sexual minorities occur across all cultures, and the levels of gay and bisexual people in populations have been quite stable over time. Our hypothesis predicts that bisexuality and people who identify as “mostly straight” should be more common than people who identify as exclusively gay, and this is the case. Recent genetic analyses confirm hundreds of genes influence sexuality in complex ways. Each person’s genetic makeup is unique, so it would be highly unlikely to find two people with exactly the same set of genes influencing their sexuality.īorn this way? An evolutionary view of 'gay genes' We quite randomly inherit half our genes from each parent. Thus, variation is expected, and individuals fall along a spectrum ranging from a majority who are straight, to a minority who identify as gay.
Our hypothesis for the evolution of homosexuality would predict this kind of variation in human sexuality, and can help explain why it is generally stable across cultures. We believe sexuality is a highly complex trait, interwoven with sociality. Attraction, sexual behaviour, social bonds and desire all contribute to its complexity. Height is another feature influenced by hundreds of genes, many of which interact with our external environments in complex ways. We see a continuous variation in human height – some very tall and very short people exist. We might draw on nutritional ecology to explore the evolution of human height, but would not feel the need to introduce special evolutionary arguments to explain the existence of tall or short people. Similarly, we think asking how gay sex and attraction evolved is the wrong question.Ī more useful question to ask is: how did human sexuality evolve in all its forms? They are simply exhibiting natural, genetically influenced variations in height. In doing do, we acknowledge homosexuality does not present a paradox needing a special explanation.
