The Year in Evolutionary Biology 2012, Volume 1251

This fourth installment of "The Year in Evolutionary Biology" series includes reviews on competition and the evolutionary dynamics of mutualism; rapid Hox gene evolution and the evolution of body plans; the evolutionary and conservation consequences of inbreeding-environment interactions; evolution and development of character displacement; applications of information theory to evolution; and gene duplications.
