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 :)
