At present, more and more research has proven that homosexuality has a genetic basis and is a product of evolution, but there are still some mysteries that cannot be solved about homosexuality. Below are several hypotheses about the origin of homosexuality, let's take a specific look.
Kinship Selection Hypothesis
Homosexual individuals do not need to invest time and effort in their own reproduction, perhaps they can help relatives raise offspring, ultimately benefiting the potential homosexual genes in these children through evolution. One study investigated gay men in Samoa in the South Pacific. Samoa is a more traditional society. The local gay men are called "Fa'afafine". They do not have children and can be accepted by all the society, especially by their blood relatives. These gay men have devoted a lot of energy to their nephews - these children have 25% of their genes on average.
Social Reputation Hypothesis
Anthropological evidence shows that in the pre industrial society, gay men were more likely to become priests or priests, and their heterosexuality relatives also gained a higher social reputation, and thus had reproductive advantages, so that any common homosexual tendency gene was continued. Unfortunately, this hypothesis has not been confirmed yet.
Group selection hypothesis
Most biologists believe that natural selection occurs at the level of individuals and their genes, not in groups. But humans may be an exception; Perhaps a group that includes homosexual individuals is better than a group that is all heterosexuality individuals. Anthropologists Sarah Hedi and others pointed out that during most of human evolution, raising offspring was not exclusively the preserve of parents (let alone mothers). Our ancestors had many quasi maternal behaviors, and those who were not parents of their children, especially other blood relatives, were involved in the task of raising offspring. It is reasonable for Homo sapiens to develop such a system, as among all primates, the newborn of Homo sapiens is the most helpless and requires the most energy from adults. If there are enough caregivers in the population who are homosexual, the entire population will greatly benefit from it.
The above is the mystery of the origin of homosexuality, for readers to understand the relevant knowledge of homosexuality.
