This project was prepared as part of a BioQUEST faculty development workshop entitled BioQUEST Summer Workshop 2007 at Beloit College in June 2007. The BioQUEST Curriculum Consortium is committed to the reform of undergraduate biology instruction through an emphasis on engaging students in realistic scientific practices. This approach is sometimes characterized as an inquiry driven approach and is captured in BioQUEST's three P's (problem-posing, problem-solving, and peer-persuasion). As part of this workshop groups of faculty were encouraged to initiate innovative curricular projects. We are sharing these works in progress in the hope that they will stimulate further exploration, collaboration and development. Please see the following links for additional information:

Brief Overview:

Simple study of the rates of evolution of lactose intolerance in pastoral and agropastoral people in Africa. We used the backwards model of DEME to estimate selection coefficents that are consistent with current allele frequencies and the development of agricultural and pastoral societies.
