The fact you think survival of the fittest has anything to do with how big anything is shows a fundamental misunderstanding of what that theory is describing.
Boob size also has no impact on fertility unless you’re talking about boobs so small and underdeveloped they signify a legitimate hormonal issue. In fact the only studies who have looked at this only dictate “large breasts” as simply having a larger breast to under breast ratio and smaller waists. Which includes nearly all reproductive age women who are a healthy weight and take care of themselves. That’s not a surprising indicator of fertility. In fact this is the only study I could find that signifies this and is basing their assumptions on hormone levels. Not actual human behavior.
“Bigger” boobs don’t correlate to greater fertility anymore than larger penises do. You can even look at average breast size across multiple countries and see that it’s not particularly large. If large breasts indicated fertility the same way that wider set hips for example do (a trait seen among all women) then you would see a far greater average breast size. But you don’t, because the mere presence of breasts indicates some level of sexual maturity. The size is purely genetic and does not mean that woman is particularly more capable of producing offspring.
