The evolution of evolvability became a topic in the 1990s, and since then, it has progressed from controversies about its radical or conventional nature to a mature research program with hypotheses motivated in evolutionary theory and theoretical population genetics. Evolvability is an outcome of a variety of organismal traits, and it evolves along with these traits. In this chapter, we first review the theoretical basis for the main modes of evolution of evolvability, including adaptation at various levels; contingent evolution based on indirect, canalizing, and congruent selection; and neutral evolution, including systems drift. We then present an overview of organismal properties that may influence evolvability and provide some selected reviews of their possible modes of evolution.
