Here is much more, interesting throughout, hat tip to The Browser.

Hard to imagine that asexuality would be an evolutionary stable population.

One generation and pfft.

First of all, of course, this argument doesn’t hold water for homosexuality and so it doesn’t hold water for asexuality either.

Assuming there’s no conceivable benefit to a parent for having the occasional non-reproducing offspring there’s still the little matter of vast numbers of people being shoved together by parents or circumstances where they’re expected to reproduce whether they like each other or not, let alone whether they like sex. There might be some reproductive hit for not having functioning reproductive systems, period. But that’s clearly more common than simple lack of interest. And yet the species somehow soldiers on.

So.

For whatever reason, as long as asexuals, like anyone else, are able to manage to have enough sex to reproduce 2.2 times on average — and like most people in history subject to social expectations plus social and familial pressure they largely have been — then pop evolution isn’t going to answer anything.

Clue #1: if you’re averse to reproducing in the first place, but your social and possibly physical success depends on it (children being most people’s retirement policies anyway) then you’re probably going to “invest” a lot more in the success of the children you do have than people who consider sex a recreational activity as well as a form of economic activity.

Clue #2: As the photo Tyler chose suggests, people who aren’t very interested in sex may have considerably more energy for other, potentially more productive activities. With the result that any children fortunate enough to be born to asexuals are likely to benefit from their parent’s additional enterprise.

Fig, When I looked up the definition, it would seem to rule out your premise: “For whatever reason, as long as asexuals, like anyone else, are able to manage to have enough sex to reproduce 2.2 times on average” Sorry, not trying to offend anyone, and apologize if I did.

Kin selection. Relatively few traits are 100% genetic. If this is only partly genetic, then you don’t need the asexual people themselves to reproduce successfully, you just need their non-asexual relatives to reproduce enough to pick up the slack. (This is one of the leading hypotheses explaining homosexuality.) Perhaps asexuals help their relatives be fertile in some way, or perhaps the relavent gene only sometimes produces asexuality sometimes and other times produces more beneficial traits.

It is not “one of the leading hypotheses”. It has been shot down by, I believe, Pinker, among others. Much more promising is one about the gene that causes women to have more children, and men to be gay. Something similar may be going on with Asexuals, or it may be completely environmental.

The most plausible explanation I’ve heard is Greg Cochran’s pathogenic theory.

It is on occasions like this that I (briefly) understand the social innovation fatigue that must motivate social conservatives. Really, we all have to be informed about “asexuals”, who are apparently identical to “sexuals” in every important respect (they even masturbate at the same rate, according to the interviewee) save their peculiar desire to affiliate with yet another trendy, internet-organized lifestyle sect.

Benny Lava August 21, 2011 at 10:28 pm

It was at the idea that an “asexual” person frequently masturbated and had pleasure from an orgasm but claimed not had sexual pleasure that this became just another Facebook group completely devoid of any real meaning.

Miley Cyrax August 21, 2011 at 4:58 pm

Yeah I am an asexual too. I just have sex with hot girls out of the kindness of my heart. *Rolls eyes*.

jon August 21, 2011 at 5:04 pm

why do i read MR? pretty much giving up and just reading the Browser now… its all Tyler posts.

Tony August 21, 2011 at 5:22 pm

I so call bullshit on all of that.

dirk August 21, 2011 at 5:58 pm

You guys don’t read enough Roissy. A man seducing a woman should display disinterest. Claiming to be asexual is one way to do it.

Yancey Ward August 21, 2011 at 6:55 pm

I had same thought- this guy is probably getting laid left and right by women looking to “cure” him.

Jim August 21, 2011 at 7:37 pm

Men, more likely.

Yancey Ward August 21, 2011 at 9:00 pm

Possibly, but it would still be a hell of schtick.

Cake, please August 21, 2011 at 6:52 pm

God damn your skepticism. We do party hardest.

Larry Siegel August 22, 2011 at 12:26 am

@bill: I am very difficult to offend, but you managed to do so with your second sentence. It was kinda obvious.

And you misspelled “evolutionarily.” Inexcusable :-)

Andrew' August 22, 2011 at 7:56 am

It’s a statement about how evolution works, or people who think they understand it, or people who think it is a litmus test for support of science because it is supposedly required for making scientific predictions, because only people who really understand evolution can be pro-science.

Wait a minute... August 22, 2011 at 5:53 am

If an asexual isn’t interested in sex, how can he be the “hardest”…?

Joe August 22, 2011 at 9:08 am

I was wondering that myself. How do asexual men get erections if they are not attracted to the person? Do they have a more difficult time in bed or require more stimulation/medication?

Andrew' August 22, 2011 at 9:17 am

Why would he go to parties?

Silas Barta August 22, 2011 at 1:57 pm

To meet the glitterati?
