Directed Evolution is a way of making better proteins than those found in nature. This platform technology enables us to make improvements to the properties of the proteins we manufacture in plants. There are many different ways of doing Directed Evolution, but its essence is very much like natural evolution. Diversity is generated in a gene of interest, and then the products of many diverse genes are screened for improved functionality. The screening is usually by way of high throughput technology, since the more individuals screened, the greater the probability of finding a superior product. Directed Evolution differs from natural evolution in that the unit of screening is usually a single gene, rather than a whole organism. Furthermore, in Directed Evolution the investigator determines what property is desirable, rather than a natural selection.
