Nina Jablonski’s conducts research on the evolution of Old World primates in relation to changing environmental conditions. The two major foci of her research now are the evolution of Old World monkeys, and the evolution of human skin and skin pigmentation. The “monkey evolution project” involves field work (primarily in China), analysis and comparative study of fossils, and study of specific sites and fossils in the context of environmental change in the last 10 million years. The “skin project” currently involves study of the evolution of skin pigmentation in human in relation to culture, technology, and diet in the last 50,000 years, and studies of the health implications of skin pigmentation for modern people. Both projects involve collaboration with teams of international investigators.
