What is (lab) directed evolution?
Directed evolution is the technique of controlling an organism's evolutionary trajectory such that its descendants have more of a desired properties. Most often, the engineers will have a strict control of the organism's environment. By controlling the environment and responding to the organism's simultaneous adaption, an organism can be directed to have novel or desirable properties. In particular, the directed evolution of microorganisms is more easily achieved due to their short generation time, high cell density, and isolated environments.
