This material is part of a larger web site. Teaching evolutionary theory is foundational for all biological sciences and a key aspect of overall science literacy. The conceptual framework for understanding evolution relies on thinking clearly about evolutionary trees (phylogenetics) and how geological history influences biological processes and diversity. Central to a student's comprehension of evolutionary research is an understanding of how scientists infer evolutionary relatedness and how they integrate geographic data. To address these concepts, we developed a series of lessons suitable for a typical introductory biology course in which students learn to infer phylogenies for the plant family, Crassulaceae. In the first part of the lesson, students develop phylogenetic hypotheses based... Show More
