This photo shows Penn State University's Tracy Langkilde, who studied the mating behavior and blue-color patterns of fence lizards to assess the evolution of sexual dimorphism. Her mating-behavior studies of lizards in three southern US states have revealed which females male lizards find to be the sexiest. The research provides insight into the evolution of male-female differences. More information is online at http://science.psu.edu/news-and-events/2013-news/Langkilde10-2013.
