| Open AccessEngineering is evolution: a perspective on design processes to engineer biology
Evolutionary and rational design approaches are commonly used to engineer biological systems but are typically seen at odds with each other. In this perspective the authors argue for the concept of an evolutionary design spectrum to help unify and compare these design methodologies to support more effective biological engineering.
