This resource will introduce you to cladistics, a classification system that scientists use to show the relationships between species. In this system, relationships between species are shown on a cladogram, a diagram that is similar to a family tree. An interactive cladogram allows you to explore the relationships among various kinds of living things and to view information and pictures about them.
This is a good resource for students to explore individually or in small groups. Since this resource can be used to explore a variety of topics and ideas, you may wish to provide students with guiding questions to help focus their attention on the concepts that you are trying to teach.
