Local fitness environments along an evolutionary path

Issue Image

The image depicts local fitness environments along an evolutionary path. The surfaces are based on measured data, and show the changes in fitness that can be achieved by a single base pair substitution. The first disc represents a duplicate repressor-operator pair, while the last represents a diverged pair. In this manner, a highly complex, multidimensional fitness landscape can be portrayed. The simulated paths explain why independent protein-DNA interactions can evolve rapidly (see Poelwijk et al).
