This page should help students grasp the fundamental concepts of systematics through a series of interactive exercises. These exercises begin with a simple example that requires a cladogram with minimal reversals and convergences.
Subsequent exercises require inclusion of additional species.
In the first exercise, systematic relations among several taxa are considered. These taxa include broccoli, toad , human, horse, common zebra, and Grevy's zebra. The objective of this exercise is to begin with a straightforward example of interactive classification. The relations among these species are displayed in the diagram to the right. This exercise requires the addition of a new species, an okapi.
