Why Cladistics?
This lesson is based on an article that explains what cladistics is, why it is useful, how it is applied, and what its limitations are. Students will learn that biological classification is intimately associated with evolution; that there are many problems encountered in classification, which is evidence that the living world is a work in progress, and evolution provides an explanation for those problems. The resource explains that cladistics is one of several ways to show relationships, each addressing different problems in different ways.
