As breasts are designed to feed babies, why do women have two instead of just one?
In: Biology
Because nature does not “design” everything to be just enough. We have two lungs instead of one. We have two kidneys but only need one. We’re bilaterally split, meaning we often have two of something, or when we have one, it’s often made of symmetrical parts. Two breasts can feed two children at the same time, or a mother can alternate between them for a single child.
