    Sexual selection pressure is massive in evolutionary systems. You’re forgetting that fitness is an indirect result of what is ultimately sexual selection pressure. A lot of people think it’s fitness first, sex second, but it’s actually the other way around, sexual selection plays a larger part, and is supposed to imply fitness, but doesn’t always. Without sex there is no reproduction, and therefore no mutations. Anyways, just remember, in evolutionary systems, they are not directly selecting for traits, they are selecting traits through the abstraction of sex and sexual selection. Sex is king here. IDK it’s weird but it is what it is.

      Sexual selection is a theory thrown around but afaik the work hasn’t been done to show this is the sole cause. Enlarged breasts may have some reason to exist beyond sexual identification - there’s not a lot of mostly bald mammals that walk on two legs so theres not a lot of good opportunities to spot convergence in features.

        sure but why is it relevant? OP isn’t saying that it is the sole cause.

        careful with the straw, you might accidently build a straw man out of it :)
