Abstract

Interpreting cladograms is a key skill for biological literacy. In this lesson, students interpret cladograms based on familial relationships and language relationships to build their understanding of tree thinking and to construct a definition of “common ancestor.” These skills can then be applied to a true biological cladogram.
