The tree of life is a branching tree, showing the relationships bettween different groups of animals. Below is a very simplified tree of life. If you have a look at the tree you will see that all the sub-groups of the vertebrates are on the same branch - they are more closely related to each other than they are to sponges, for example.
Click on the different animals on the tree below to learn about each group.
Think about the different characteristics of each sub-group and why the animals in them have been classified together.
