Science Quote by Peter R. Grant

Strip away the romance-novel fog and you get a blunt, almost mechanical picture of desire: courtship as signal traffic. Peter R. Grant, writing as a scientist steeped in evolutionary thinking, isn’t trying to flatter human exceptionalism. He’s putting mating on the same analytic plane as bird song, plumage, dances, and rituals across species: behaviors shaped to be read.

The intent is precise: courtship isn’t just “expression,” it’s communication under pressure. A display is a package of information meant to move another organism’s decision. The subtext is that attraction is rarely private. It’s performed, calibrated, and, crucially, evaluated. “Signals” implies an audience; “transmit” implies cost and reliability; “behavioral displays” suggests that bodies function as instruments. Even the sterile phrasing does work: it nudges you to notice patterns you might otherwise label as spontaneity or “chemistry.”

Context matters because Grant’s world is sexual selection and honest signaling: traits persist when they successfully advertise fitness, resources, or intentions, and when cheating is constrained by biology or social punishment. The line quietly smuggles in competition as the engine of style. Displays don’t evolve in a vacuum; they escalate because rivals exist and preferences shift.

Read culturally, it’s a reminder that what looks like individual “rizz” often sits on deep, inherited scaffolding. The modern twist is that humans have upgraded the stage. Our courtship signals travel through gyms, Instagram, resumes, playlists, and politics, but the underlying logic Grant gestures at remains: being chosen is, partly, being legible.
