The theory of evolution is a complex one, so Bill Nye broke it down using something we all can understand: Emojis!
Cartoon smileys represented molecules, and Nye explained how they hooked together—"probably with energy from the sun"—and "accidentally found ways to reproduce themselves." These molecules "could not make perfect copies of themselves," and they kept reproducing these imperfections, Nye explained in a Mashable video that was part of G.E.'s Emoji Science event.
"And pretty soon you had complicated things," said Nye, as emoji after emoji continuously popped up onscreen. These things, like bacteria, continued to reproduce, and they became things like multi cellular organisms—like barnacles, sea jelly, and as Nye joked, "even my old boss!"
