Using the final cladogram on the next page, you can trace back the natural history of each animal included in the cladogram, noticing major adaptations  that each animal evolved, in order.  Scientists study both fossils and living animals to help discover how animals are related in order to create cladograms  like this one.

To learn more about cladograms, you can view a powerpoint presentation or learn about the cladogram my 7th grade students created.
