Is this the affinity or core part of intersexual selection (males fighting for access to females)?
If females are bound to flock to objectively more attractive man 'A' in the majority of cases, would killing him put odds in your favor? It's all relative, no? If a guy is better looking than you and you kill him, he's obviously no longer better looking and alive -- so he can't reproduce. If you killed every better looking man than yourself, wouldn't you become the next best looking man? Sounds about right.
But is this not the core reasons for mating? Kill off all the good looking men and then you're hottest.
Since no guy alive can be more attractive than you, you have sex with all of the women. Not crazy.....?
I mean in theory of course..... we know what makes men sexier -- jaws, cheekbones, eye shape, height, size/muscles, symmetry, facial width to height ratio, skin complexion/coloring/etc. So yeah....
