How does behavior evolve? We're interested in the ecological factors that influence social behaviors and the physiological mechanisms that underlie those behaviors.  Most of our work uses lizards in the genus Anolis, or anoles, but we're also beginning to explore the diversity of lizards that occur at our local field sites in south-central Texas.  We use field observations, laboratory experiments, molecular genetics, neuroendocrine techniques, and comparative methodology to explore behavioral evolution.
