The Evolved β-Galactosidase System of Escherichia coli
The overall objective of research in experimental evolution is to understand the variety of ways by which organisms can evolve new physiological functions. How does an organism that is already well adapted to its environment evolve a new function to cope with an altered environment? The synthetic theory of evolution does not really address the problem of the evolution of novel functions, nor does population genetics deal with the appearance of new functions.
