Mammary glands–a.k.a. “breasts”–are so important to the survival of the species that biologist Carolus Linnaeus put them front and center in choosing the name “mammals” for our class of animals long ago. It’s true that breasts are specially designed to produce that life-giving fluid: milk! The lactating mother can serve as her infant’s sole source of nutrition and immunologic support.
