Abstract

Systematics and phylogenetic reconstructions are among the most difficult concepts for students to understand in introductory biology. They are also fundamental to understanding how biologists view the evolutionary history of the world around us. This exercise uses models of Caminalcules to teach basic tree construction and interpretation. Students first construct a tree of by hand, and then they then use the computer program Mesquite to construct and analyze a more complex tree.

Keywords:  systematics, phylogeny, caminalcules
