The Evolution of Color Vision in Monkeys
From Nucleotides to Ecology
Merle K. Heidemann
Peter J.T. White
James J. Smith
This case study examines the evolution color vision in Old World and New World monkeys from multiple biological perspectives. This integrative approach employs both problem-based learning techniques and directed questions as students move through a series of modules that takes them from nucleotides through alternative alleles to protein function to ecology and phylogenetics. The modules (ecology, cell biology/protein function, genetics and phylogenetics) can to be used in any order as dictated by course objectives and structure. The case study is appropriate for a basic undergraduate biology course or for genetics, ecology and cell biology upper level courses. A key feature of the case study is weaving evolutionary thinking into the biology curriculum. The research phase of problem-based learning is supported by a series of slides and simulations that can be downloaded from the authors' site where they are stored, edited, and used according to instructors' needs.
