Bottles aside, most things are “aerodynamic” because that’s what happens when something grows out from a point. Hard edges aren’t natural, except in some very specific circumstances (crystals mostly). If something grows gradually, it’s more “energy efficient” to be rounded and bulbous (least surface area per volume). And nature follows the principles of least effort.
