It really makes my day whenever I read “scientific theories” that don’t fit the main paradigm or predictions of evolutionary theory. The evolution of homosexuality is one of my favorite paradoxes, maybe with the exception of gender evolution/sexual reproduction, that I’m going to save for another OP.
It doesn’t take Einstein to notice that the evolution of homosexuality is not only a paradox but it totally contradicts the driving force of evolution, which is supposed to be reproduction. Since homosexuals can’t reproduce, not in homosexual relations, a problem for evolutionary theory arises. Why would homosexuality evolve in the first place? But more so, why would natural selection preserve homosexuality?
However, as it is with many, many other evolutionary paradoxes the theories to explain them abound… Check out this one of the evolution of homosexuality:
