Understanding the ability of organisms to evolve and the rate at which evolution can occur is crucial if we are to predict the fate of populations and species facing rapidly changing environments.

However, predictions about trait’s evolvability are often made difficult by the correlations among traits that influence and possibly constraint evolution.  Using both field studies and lab experiments and including several model organisms such as plants and invertebrates, we ask several questions related to the general problem of evolvability and adaptation under various types of selection.
