Evolution, Just Like a Game of Telephone

GrrlScientist asks, have you ever played the game Telephone in which kids form a line and a message is repeated in whispers from one to the other? Remember how distorted those messages were by the time they reached the end of the line? This game, and others like it, can be used to teach students how evolution works. In a take on "telephone," a video created by videographer Clement Valla shows 500 people trying to trace over an existing line, GrrlScientist says. But, she adds, "as each person copies the previous person's effort, the original straight line morphs into a chaotic mess of random squiggles." Just like Telephone this experiment shows how evolution works by building on mutations and DNA copy errors.
