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.
Yes.
We humans are very well adapted to tell humans apart, penguins are very well adapted to tell penguins apart. They have gender specific mating calls for example.
I think this means that they only choose last years partner 15% of the time. Still higher than random chance, but in no way dependant on their partner.
Was looking up something else on Wikipedia and stumbled onto this fact. I know this is not exactly related to the point you wanted to make, but I might as well share it.
From the penguin documentaries I watched as a kid, I feel like the “leaving eggs behind” might involve relentless bullying.
The news say Eastern Ukraine, though take that with a grain of salt as I haven’t been there personally.
I never bought any Apple product and thought they were overhyped, so it might be easy enough for me to say, but no, I personally wouldn’t have been Ok with it.
I can see more people begrudgingly using it if Apple did it though.
The left-leaning parties disappointed me with their posters this election. There was 1 that said “Set a mark against fascists” and showed an anti-afd protest, and another with a similar message.
I know they are the nazi party, I want to know what YOU stand for. I’ll have to guess political scientist found out nobody really changes their mind from a poster, so the only thing they do is remind people of their party that they need to go out and vote.
If that’s the case, the poster may be better than I give it credit for. Still, doesn’t seem to have worked.
Our Minister of transportation has been a disaster for our most climate minded government yet.
He continuously refuses to present any plans on how to reduce emissions in his sector. His emission reduction targets for the past few years were missed, but instead our climate bill was changed so it doesn’t have immediate consequences as long as other sectors meet their targets. Investments in communal and private rail were cut by 20 million €, while 150 Million were given to Volocopter, a start up for personal-use passenger drones. “State-owned” rail did see minor increases in investments, but most of that money is locked for now until the government and “Die Bahn” company agree on financing it.
The only good new thing in transportation right now is the 49€ a month ticket for all public transport in Germany, and even that fails to make commuters switch to public transport as public transport remains unreliable and inconvenient outside of cities.
…what do you mean, “open-source”?
He’s a Christian like any other and Christians will have to recognize that their beliefs are responsible for a lot of homophobia, instead of saying that anyone who makes them look bad is not a “true” Christian.
I am already petitioning for a de-federalization with any instance that allows those swears. Not in my good Christian Fediverse!
I never said that. What I meant is that a behaviour, which benefits a species as a whole but reduces one individual’s fitness, is not evolutionary competitive. It’s evolutionary game theory, like the prisoners dilemma from normal game theory.
And to determine if some behaviour is such a dilemma, you have to consider costs and benefits of it, which is not at all clear in natural situations. That’s why I said it needs to be studied.
But I must concede, I sort of assumed what exactly you called an evolutionary advantage. Common homosexuality in penguins or not discriminating against homosexual individuals in penguins have very different analysis here.
