Abstract
The evolutionary process as imagined by Darwin 150 years ago is evident not only in nature but also in the manner in which naked nucleic acids and proteins experience the “survival of the fittest” in the test tube during in vitro evolution. This review highlights some of the most apparent evolutionary patterns, such as directional selection, purifying selection, disruptive selection, and iterative evolution (recurrence), and draws parallels between what happens in the wild with whole organisms and what happens in the lab with molecules. Advances in molecular selection techniques, particularly with catalytic RNAs and DNAs, have accelerated in the last 20 years to the point where soon any sort of complex differential hereditary event that one can ascribe to natural populations will be observable in molecular populations, and exploitation of these events can even lead to practical applications in some cases.
