Why is nature so cruel?
>>
How does this help ensure the survival of the species?
>>
>>5134069
It's probably some kind of marker for healthy genes
>>
Foids only like Chads regardless of the species.
>>
>>5134069
At a guess, it makes them look larger and scarier to deter competition
>>
>>5134068
Wait until you learn how the males deal with it
>>
>>5134069
Dominant male> stronger traits> stronger genes> more fit offspring
Flanged males get their prefered pick of the ladies. The lessers get sloppy seconds if they can sneak it past the boss.

Orangutans are looksmaxing. Keep them away from anyone who teaches them about mewing.

it doesn't, evolution is not an algorithm that selects for species survival, it selects for gene propagation regardless of how the gene is propagated. Evolution happens at the genetic level, all that matters is how well the gene does.
there are genes that are very successful yet do not benefit the survival of the individual, like the tail of the male peacock. It is energetically costly, attracts and is caught by predators, and has no benefit to survival in any way. It is likely that at one point in the species' evolutionary history, having a relatively long and colorful tail represented good nutrition and genetic quality, but the current state is clearly detached from any real measure of quality. A male might be otherwise small and weak and of poor health, but if they have a big tail that's enough.
The orangutan flanges are associated with being a dominant male that controls territory, which produces testosterone, which causes the flanges to grow. Sex hormones can be socially sensitive. But certainly this does not benefit the survival of the species, because many or most males are without flanges. The species would survive much better if more males mated, because it would mean larger populations and more genetic variability. Even if many males had worse genetic quality, the quality of the species would improve by natural selection, and the species would be far more widespread and have more opportunities for evolution. Sexual selection is essentially a hijacking of the evolutionary algorithm by complex social behavior.
So why does this happen at all? Because evolution happens at the genetic level, and the flange genes are successful. It doesn't matter if the feature has terrible consequences for the individual or the species, even if the outcome of the gene being popularized would cause the species' extinction, so long as the gene alone is successful it will persist.

I'm a woman who tends to prefer less "manly" traits in men: less hairy, narrow shoulders, not buff. I wonder if it's common across species to have a minority of females like this.

Now apply this same idea to humans (women) and suddenly a lot of things make sense lamo
>>
>>5134267
Human mating involves much more than looks
>>
>>5134234
It's normal.
Women tend to preference less masculine faces and forms the further from ovulating they are and more masculine ones the closer they are to it. If you're really locked into one it's likely a hormone imbalance guessing birth control or eating disorder.
