Caitlin Schrein earned a master’s and a doctorate in evolutionary anthropology from Arizona State University. She has conducted fieldwork searching for early primates in North America, monkeys in Europe, apes in Kenya, and the first hominins to leave Africa. Her doctoral research examined the relationship between human evolution education and students’ interest in science and their decision-making about social issues with a scientific basis, such as climate change. Caitlin currently lives in Washington, D.C., where she works as a science writer and spends her free time going to museums, hanging out with her dogs, tweeting about fossils and evolution, and watching old movies.
