Translation of title - "Babes with curves are hot!!!"

tl;dr there's no pics.

This is just a confirmation/refinement of something known for a very long time. I just finished reading http://www.amazon.com/Evolution-Desire-Revised-4/dp/04650080... , if you're interested in such stuff it's a really good book. Most of human "mating behaviour" is understood to a pretty amazing degree if you read the right things. Doesn't make actual mating any easier :p but it puts a lot of perspective into it.

Didn't Sir Mix-a-Lot already formulate this as "My anaconda don't want none unless you've got buns, hon"?

At the risk of sounding snobbish, brains turn me on way more than bodies. Brains last, bodies go pretty quickly.

Maybe I'm just poorly reward-motivated, though. My wife and I effectively lived together for 3 years before getting married, and we both waited until marriage for sex.

    Brains last, bodies go pretty quickly.

Neither last without constant care & maintenance.

Granted, but the stereotypical "ideal" body simply doesn't last through a lifetime, no matter how it's maintained, though a mind can last through even the longest life.

Interestingly enough, Waist-to-Hip Ratio (WHR) has come up here before: http://news.ycombinator.com/item?id=908868

I kinda' prefer the golden ratio, myself. NSFW: http://www.reddit.com/r/nsfw/comments/9v6zt/curvy_in_all_the...

Wonder why there's tons of those articles and they talk about fertility cues but never deliver any solid data on this.

it's always 'women prefer this mans face because of fertility cues', 'man prefers this ass because of fertility cues'.

This is relatively solid data, actually. They used a fMRI to watch the blood flow (indicative of activity) in the "reward center(s)" of the brain with a higher incidence than without that 0.7 ratio.

* shrug * more proof that the super-thin look is horrible for both women AND men.

I'd like to see the data on the hip-waist ratio indicating higher fertility. Seems to me most women are capable of bearing children.

The baby has to fit through the hole in the middle of the pelvis. If a women's hips are narrower I would suspect that there is a higher likelihood of her birth canal being narrower meaning less chance of a successful natural birth.

You really have to discount c-sections and such when thinking about 'fertility' since it would stand to reason that a lot of reactions are instinctual.

> I'd like to see the data on the hip-waist ratio indicating higher fertility

You might have trouble with that if you follow my advice and ignore medical 'intervention' like C-sections since in previous years doctors would do a C-section at the drop of a hat (IIRC, the rate used to be 80% whereas now it's around 60%).

[edit] further investigation makes my claims to be a bit 'pie in the sky:' http://en.wikipedia.org/wiki/C-section#Incidence

Here is another relevant tidbit I found while investigating:

  A previously unexplored reason for the increasing section rate is the
  evolution of birth weight and maternal pelvis size. Since the advent of
  successful Caesarean birth over the last 150 years, mothers with a small
  pelvis and babies with a large birth weight have survived and contributed to
  these traits increasing in the population. Even without fears of malpractice,
  without maternal obesity and diabetes, and without other widely quoted
  factors, the C-section rate will continue to rise simply due to slow changes
  in population genetics.

Good point about the c-sections, but still, I am not entirely convinced. For one thing, that wouldn't explain waist/hip, or would it? It would then all be hip, and women would get increasingly larger hips? Also, thinking about Asia, I think women are very tiny there, and they still get children. Their babies are probably smaller, too. But making bigger and bigger babies does not seem to be a "goal" of evolution, either. Otherwise a woman's height would be attractive, which I don't think is the case.

Ah, my mistake. I've seen nothing "conclusive" on that, and I'd highly suspect that the majority of it is just through reasoning.

Slim / average (not anorexic, not overweight) is indicative of health, which is indicative of both healthy babies and a more careful lifestyle, thus more likely a better mother (biologically! not implying deeper connection here).

Meanwhile, wider hips imply a wider birth canal. Combine the two, and you get the hourglass figure, and a relatively arbitrary (/ personal) choice to use 0.7 instead of, say, the golden ratio. (or e/pi, or any other ratio)
