It takes two penguins working together to care for an egg, if one penguin dies the remaining penguin can’t hold the egg and feed itself, so either a couple steps up or a lone penguin joins the remaining penguin, having several homosexual couples who are on standby to take care of orphan eggs is a clear evolutionary advantage.
I’d be cautious with saying evolutionary advantage here.
I don’t believe the “Gay Uncle hypothesis” any more than the somewhat debunked “Grandmother Hypothesis”, which aimed to explain menopause with biological altruism. Just because we could think of a way in that it might be advantageous for a species doesn’t mean it’s advantageous for an individuals fitness.
Of course, it can be still an advantage, but we’d only know with more free, uncensored research.
