Swedish scientists have wondered about the reasons for the spread of homosexuality in living beings, given the lack of benefits. Homosexuality does not lead to the emergence of the offspring and in theory these individuals would have to disappear, but they appear again and again. Light on this question spilled observation of the beetles gay. It turned out that all the fault of a certain gene. In males it contributes to the development of homosexuality, but it makes females more fertile.
On their study, the researchers of Uppsala University reported in the journal BMC Evolutionary Biology. The article says that the researchers examined four-spotted chaser beetles weevil (Callosobruchus maculatus). The researchers were able to bring beetles that had a greater tendency towards homosexuality. And here’s further observation showed that when males from one of the offspring showed signs of homosexuality, their sister increased reproductive function.
It turned out that females and males are divided between the vast number of genes, including genes that can determine homosexual behavior. But if males due to the presence of these genes began to show sexual interest in other males, then the females started laying more eggs than before.
The homophobia in different countries, the main argument in disputes with the LGBT activists is the claim that homosexuality is contrary to nature and cannot bear anything positive. Swedish scientists thus confirmed the opposite theory, that under certain circumstances the genes of homosexuality give the benefit of sight, increasing the population. Earlier, a similar theory was made by Georgian and biologist George Chaladze.Related posts:
