1<p align="left">Reading phylogenies and thinking clearly about evolutionary history is a cognitively challenging task. This activity helps students overcome common misconceptions, allowing them to use phylogenies to understand evolutionary relationships as scientists do.&nbsp; This activity is a variation on the Great Clade Race (Goldsmith, ABT, 2001) in which students solve a logic puzzle reconstructing the map of a hypothetical race course.&nbsp; In this version the race course is actually the phylogenetic tree for six familiar animals. Students then explore the evolutionary concepts represented by the map. In the activity, students learn basic terminology and how to read a phylogenetic tree.&nbsp;</p>  1<p>Reading phylogenies is a cognitively challenging task.
