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.
Does evolutionary pressure only exist on individuals? I’ve never heard that. There’s a wide variety of species that are highly socially organized, do you not accept that that’s through evolutionarily pressure?
From the penguin documentaries I watched as a kid, I feel like the “leaving eggs behind” might involve relentless bullying.
