Scatterplots show the evolving populations of hammerheads across multiple rounds of evolution. Hammerheads copied by the lower-fidelity polymerase (52-2) drift away from the original RNA sequence (white contours) and lose their function. Hammerheads copied by the new higher-fidelity polymerase (71-89) retain function, with new functional sequences emerging over time.
