in‐vitro evolution

The complexity of the biological world has arisen through a process of evolution. The study of that process is important in order to understand the continuing evolution of life on Earth, as well as to harness evolution to create new biological tools for human applications. In vitro evolution is a laboratory re-creation of the natural process that allows scientists to watch systems evolve in real time and to control the selective pressures to which molecules and organisms are forced to adapt. In vitro evolution has been used to study the evolution of organisms like bacteria and yeast, as well as biological macromolecules like nucleic acids and proteins. Given the complexity of biological systems, laboratory evolution may be the best way to create new biological machines to solve human problems from renewable energy to cancer.
