There is no power of naturalistic evolution to create anything demonstrated here. The Nobel Prize: Directing Evolution Nobel Prize recipient Frances Arnold joins Tim to talk about winning a Nobel Prize honor for her pioneering work in “directed evolution,” which harnesses the power of evolution to enhance products throughout society – from biofuels and pharmaceuticals, to agriculture, chemicals, paper products and more. Combinatorial procedures have become established in recent years as alternatives to rational design in drug research, particularly when no structural information is available. This article presents the principle that was originally developed by three scientists and was honored with the Nobel Prize for Chemistry in 2018. Directed evolution is a mimic of the natural evolution cycle in a laboratory setting. Evolution requires three things to happen: variation between replicators, that the variation causes fitness differences upon which selection acts, and that this variation is heritable . The Nobel Prize in Chemistry 2018 was divided, one half awarded to Frances H. Arnold "for the directed evolution of enzymes", the other half jointly to George P. Smith and Sir Gregory P. Winter "for the phage display of peptides and antibodies".

Directed evolution has been used by Arnold and others to make all manner of molecules that would otherwise require lengthy, expensive, and often environmentally unfriendly syntheses. The list of products made enzymatically includes the biofuel isobutyl alcohol and the antidiabetic drug sitagliptin.

Figure 1. Evolution towards directed evolution There are three main steps in directed evolution: mutagenesis, selection/screening of the desired enzyme property, and decision of which parental genes will proceed to the next round of evolution. The experiments can be performed in vivo, inside cells (bacteria or yeast), or through in vitro transcription–translation systems.
