Also: radiation breeding, induced mutation, directed evolution, 2018 Nobel Prize in Chemistry
Scientists speed up natural mutation, first with X-rays in plants and animals, later in test tubes for enzymes (directed evolution). Frances Arnold, George Smith and Gregory Winter shared the 2018 Nobel Prize in Chemistry.
