The Chicken Egg Came First—Why Evolution Gets It Wrong (And What That Really Means) For centuries, the age-old debate has fixated on: If a chicken laid an egg before chickens existed, how could the first true chicken emerge? Intuition suggests such a genetic leap should be impossible—yet evolution, backed by rigorous science, reveals an unexpected truth: the chicken egg didn’t just come first—it was inevitable. ### The Egg Benefits Evolutionary Biology Long Before Chickens Existed Evolution didn’t begin with chickens. Modern birds evolved from theropod dinosaurs over 150 million years ago. At some pivotal point, a rare genetic mutation in an egg-laying ancestor produced a creature with nearly all modern chicken traits—feathers, beak structure, egg-laying capability—just not quite a Chicken gallus gallus. That proto-chicken discovered the egg long before anyone classified it as such.
