>>98587600>For one, giga tits are too large for a woman to breastfeed without assistance. Right, so who's to say an alternate path for humanity's evolution wouldn't result in a social structure where breastfeeding with assistance was the norm?
>For another, the musculature required to support them would take a hormonal environment that would probably shift human sexual dimorphism to something like what spotted hyenas have. Not necessarily, it would just require a different hormonal sensitivity of the breast tissue.
>In order to hold themselves in the shapes they're portrayed as, they would need to be run through with collagen in the manner of whale blubber, and so would feel firm and rubbery instead of soft and squishyThey wouldn't need to be run through, they'd just need some kind of stronger form of cooper's ligaments.
>Human structural proteins are located in the extracellular matrix, not within cells.They're produced by the cells. What I'm getting at is that the capacity for evolution to change the structure of proteins is far greater than you imply. There's no need to adhere to existent proteins when similar but fictional proteins can realistically exist. It's all about the environment. If there were selective pressures that heavily favored soft yet shapely breasts of crazy size, evolution would find a way to provide that.
