The Field Museum's Pritzker Laboratory is a non-departmental multi-user core facility dedicated to genetic analysis and preservation of the world's biodiversity. It is shared by Field Museum curators, staff members and associated outside collaborators who constitute together one of the most diverse groups of evolutionary biologists and systematists in the world. The lab provides researchers with state-of-the-art equipment in molecular biology, enabling them to pursue the study of genetic diversity throughout the tree of life and at all taxonomic levels, from relationships among populations to classes and phyla of organisms. • Go to the web site for the Pritzker Lab for Molecular Systematics and Evolution
