Scientists Frances Arnold, George Smith and Sir Gregory Winter have won the 2018 Nobel Prize in Chemistry for research using evolution to produce new enzymes for chemistry.
They have used the idea of evolution - survival of the fittest - with the intent of making proteins that solve mankind's’ medical problems.
Harnessing enzymes and evolving them to act as medical treatment is far less harsh on the body than complex synthetic drugs, and these nobel prize winners have changed the face of medical science.
