The Royal Swedish Academy of Sciences has awarded the Nobel Prize in Chemistry 2018 with one half to Frances H Arnold and the other half jointly to George P Smith and Sir Gregory P Winter. This year's Chemistry Laureates have taken control of evolution and used the same principles -- genetic change and selection -- to develop proteins that solve humankind's chemical problems. This year's prize "awards a revolution based on evolution", and goes to scientists who "applied the principles of Darwin in the test tube".
