An animal that invested in a spine instead of just vibes.
means An animal with a backbone — a segmented column of vertebrae protecting the spinal cord, forming the internal skeleton that fish, amphibians, reptiles, birds, and mammals all share.
from From Latin vertebra, 'joint' or 'turning point,' rooted in vertere, 'to turn' — the same root behind 'versatile' and 'convert.' The spine was named for its hinge-like joints, each one letting the body bend and twist. Vertebrate itself is an 18th-century scientific coinage, when naturalists began sorting the animal kingdom by internal architecture rather than appearance — spine or no spine, turning point or none.
