Timeline reading "All ties" from the far left until "Invention of scissors, -3000". Then it's reading "Rock advantage" until a second marker called "Invention of paper, -179". The final description from there to the far right reads "Balanced".
For obvious reasons, the scissors weren't added until the discovery of metal in the Iron Age.
