You're warm, you're hairy, and your mom literally made milk for you — welcome to the club.
means An animal that's warm-blooded, has hair or fur at some stage of life, and nurses its young on milk from the mother's body.
from From New Latin 'mammalis,' built on Latin 'mamma' meaning breast or teat — the same root behind 'mammary.' The classification itself comes from 18th-century naturalist Carl Linnaeus, who grouped animals by this milk-making trait when organizing his system of biological classes, giving the whole category a name rooted quite literally in the feature that defines it.
