Evolving a protein is a useful tool in a team's compendium of tricks. With evolver play, one person may introduce their bright idea, and another person might do something completely different to improve that idea, creating a protein better than either person could do alone. As they say, "many hands make light work". In puzzle 420, although Team AD's highest soloist was in 11th place, the team as a whole came in second, due to the dedicated work of its many evolvers.
