The mission of the Peabody Museum is to serve Yale University by advancing our understanding of earth’s history through geological, biological, and anthropological research, and by communicating the results of this research to the widest possible audience through publication, exhibition, and educational programs. The Yale Peabody Museum, with its world-class collections (numbering over 12 million specimens and growing), is able to bring tremendous resources to bear in addressing this challenge. Formal collaboration was established among the Yale Peabody Museum, the Yale Institute for Biospheric Studies, and the School of Forestry and Environmental Studies. This environmental partnership recognizes the Peabody Museum as a resource and catalyst for interdisciplinary research on the earth’s history and environment, and seeks to strengthen the intellectual ties between the Museum and other groups with a shared interest in environmental research at Yale. The Museum’s collections are a major component of the research and teaching activities of the Peabody and Yale. The curators and staff are engaged in contributing new knowledge based on the Museum’s research materials and making this knowledge available to the general public and to specialized audiences. All collections are used in undergraduate and graduate teaching and research, as well as in public programs and exhibitions.
