#rationality # [[Epistemic status]] #shower-thought # Why women care more for prettiness >Why has that man fallen in love with that woman? Because she's pretty. Why does pretty matter? Because human beings are a mainly monogamous species and so males are choosy about their mates (as male chimpanzees are not); prettiness is an indication of youth and health, which are indications of fertility. Why does that man care about fertility in his mate? Because if he did not, his genes would be eclipsed by those of men who did. Why does he care about that? He does not, but his genes act as if they do. Those who choose infertile mates leave no descendants. Therefore, every body is descended from men who preferred fertile women, and every person inherits from those ancestors the same preference. Why is that man a slave to his genes? He is not. He has free will But you just said he's in love because it is good for his genes. He's free to ignore the dictates of his genes. Why do his genes want to get together with her genes anyway? Because that's the only way they can get into the next generation; human beings have two sexes tha must breed by mixing their genes. Why do human beings have two sexes? Because in mobile animals hermaphrodites are less good > ~ [[Biology/Matt Ridley|Ridley]] So women go more to the gym, eat broccoli and wear tight pants, for men. # External links - [[Halo effect]]
