scrappy Posted January 19, 2009 Share Posted January 19, 2009 This article makes a case that homosexuality may function as a form of kin selection. Perhaps gays are not expunged from the human population, as one might expect for a group that does not participate in sexual reproduction, but instead are allowed (and even maintained) to function beneficially in supporting roles to their population. Any thoughts or relevant extrapolations? Link to comment Share on other sites More sharing options...
ecoli Posted January 19, 2009 Share Posted January 19, 2009 its a sound theory, but i don't think it's been demonstrated in the animal kingdom to be true. Link to comment Share on other sites More sharing options...

Mokele Posted January 21, 2009 Share Posted January 21, 2009 I think it doesn't explain squat. Homosexuality occurs throughout the animal kingdom, including in species with little or no sociality. While on the island in question, it may give a fitness benefit, I don't think that explanation works for the ultimate cause of homosexuality itself. Whatever that cause is (kin selection or just a genetic hiccup), it needs to explain the prevalence beyond humans. Mokele Link to comment Share on other sites More sharing options...

I'm confused about your claim that homosexuality runs rampant through the animal kingdom. Does it really? I saw an Animal Planet video once of a male baboon who tired to hump another male baboon, but he was rejected. Then he went over and tried to hump a tree stump. Does this mean then he went from homosexuality to herbal sexuality? Link to comment Share on other sites More sharing options...

I especially liked the homosexual penguins with their rocks. Yes, it does seem like a natural function to me—homosexuality could carry on in a species if it provides kin benefits. I'm on the side of the argument that says homosexuality can be seen naturally as form of kin selection. (But does this have any meaning in the context of gay rights, since most scientists already agree that choice alone does not make a person gay? It would be interesting for the gay community to pick up on Hamilton and Dawkins and adopt a neo-Darwinian perspective...you know, from gay power to kin power.)

If I ever had any doubts about my heterosexuality they were crushed like grapes when I saw Brigitte Bardot in “The French Bikini.” (But, on this issue of choice, would you say a bisexual person makes such choices?

Sisyphus Posted January 23, 2009 Share Posted January 23, 2009 The thing with human homosexuality is that pretty much has to have both a nature and a nurture element. For the former, there's the fact that it's probability is closely tied to biological siblings (every older sibling you have, whether or not they have any contact, increases the probability of homosexuality). Plus, you know, common sense. For the latter, there's the fact that it shows up very differently in different cultures (in ancient Greece, almost every male practiced bisexuality, and pure heterosexuals would be deemed effeminate). But whatever the underlying basis, it's obviously not a conscious choice who you're attracted to. I mean, really, does anybody actually believe it is? (And no, the choice on whether to act on it doesn't count.) Link to comment Share on other sites More sharing options...
Mokele Posted January 23, 2009 Share Posted January 23, 2009 doesn't this statement incorrectly assume that homosexuality in humans and other animals results from the same phenomenon? How is it incorrect? It *hypothesizes* that it's the same, because that is and always should be the default hypothesis when you see a trait manifested over much of the animal kingdom. A basic rule of reconstructing trait evolution is parsimony - postulate the fewest origins and losses that can account for the observed distribution of the trait. In this case, that would mean postulating that there is a single origin, probably quite far down the evolutionary tree. Link to comment Share on other sites More sharing options...

I mean, really, does anybody actually believe it is? (And no, the choice on whether to act on it doesn't count.) Speaking about what is natural or not, what about polygamy, pedophilia, incest, and baby eating? Those are all well represented in the animal kingdom, too. And the female Black Widow spider eats her mate after mating, which is also natural. Do you think at some point we should differentiate what other animals do from what we do as humans?

iNow Posted January 24, 2009 Share Posted January 24, 2009 So there are no choices at all involved in attraction? What do YOU think? I think the answer to your question is obvious.

Do you think at some point we should differentiate what other animals do from what we do as humans? What are you talking about? I don't understand how this is a response to the text you quoted from me, nor do I really understand what you're asking me. Do I think we should excuse murdering and eating one's sexual partners on the grounds that Black Widow spiders do it? No. I'm willing to go on record saying that we should not.

scrappy Posted January 25, 2009 Author Share Posted January 25, 2009 To iNow and Sisyphus: Doesn't kin selection provide an natural excuse for non-heterosexual behavior? No, I really don't think we choose are sexualities; nature does it for us. But let me ask you this one hypothetical question: What if nanotechnology and/or genetic engineering someday (probably sooner than later) discover what causes of sexuality and find ways to change it. I suspect this will be possible within 20 years. When that happens choice will be the rule of the day and nature will take a back seat. (I can visualize a sex-change business operating like a laser eye-surgery clinic: in and out in a jiffy.) Link to comment Share on other sites More sharing options...
Sisyphus Posted January 25, 2009 Share Posted January 25, 2009 Well that's quite a big "if," frankly (I don't think it's nearly that simple, myself), but I don't know what you're really asking. What would happen? Well, if cultural attitudes are still like they are today, I would guess the majority of naturally gay people would "get it fixed" at puberty since who would willingly put up with millions of idiots calling them immoral and whatnot if they could avoid it? People who have been gay adults for a while probably wouldn't. If trends continue and it becomes more generally acceptable, most probably wouldn't both bother. Or maybe lots of people would just make themselves bisexual, cus, hey, more fun for everyone. Link to comment Share on other sites More sharing options...
