to deduce what probably happened in the past. From 1994 to 2006, she held the Irvine Chair of Anthropology at the California Academy of Sciences in San Francisco. During this time, she was recognized as a Fellow of the California Academy of Sciences and as a Fellow of the American Association for the Advancement of Science. Her responsibilities at the California Academy of Sciences included organization of the Wattis Symposia in Anthropology and publication of the edited proceedings of those symposia. Among the Wattis Symposium volumes she edited was The First Americans: The Pleistocene Colonization of the New World, which included important contributions about the nature and timing of human movements into the Americas. After leaving the California Academy of Sciences, she moved to The Pennsylvania State University, where she served as head of the Anthropology Department from 2006 to 2011. She is currently an Evan Pugh Professor of Anthropology at Penn State. Jablonski's research at Penn State has focused on the evolution of Old World monkeys, primate thermoregulation, and the evolution and meanings of human skin pigmentation. Starting in 2012, in partnership with Henry Louis Gates, Jr., host of the PBS show Finding Your Roots, she led the development of a curriculum aimed at getting younger students of color more interested in STEM. A series of PBS webisodes, "Finding Your Roots: The Seedlings" was released in 2017 and 2018 with three of the episodes earning Mid-Atlantic Emmy Awards in 2018 and 2019. Research Jablonski researches human and primate evolution. She is known for her research into human skin, and has published two books on the subject. She researches the origin and evolution of the skin and skin pigmentation and the relationships between vitamin D requirements and metabolism in the context of human migration and urbanization. In 2012 she was awarded a Guggenheim Fellowship to carry out research into human vitamin D production in natural conditions with the goal of informing public health interventions addressing vitamin D deficiency. Skin color Jablonski studies the physiological functions of skin as well as the evolutionary and sociological influences of the past and today. Early in her skin research, she published papers on the connection between neural tube defects and ultraviolet radiation, which damages folate in the skin, in the controversial and non-peer reviewed journal Medical Hypotheses. This research was put on a strong empirical footing when she, in collaboration with George Chaplin, examined
