Evolution and evolvability: celebrating Darwin 200

Many interpret the evolutionary success of whole groups of organisms, such as the vertebrates, as being the consequence of specific changes in their ancestors, no doubt driven by individual selection, but which subsequently had the effect of promoting diversification and evolutionary success, by enh ...
