Why do paleontologists make diagrams (evolutionary trees) like this? What are they trying to show?

Do:

Open the Sim in Free Explore mode and press TREE to open Tree View.
Navigate through the evolutionary tree and press each of the “i” icons on the tree branches as you go.
Read the text from each icon until you find the “i” icon that has the body structure you are exploring.
Follow the tree branches to the right of this icon to find two living species that have this body structure.
Try to find species that are very different from one another by expanding branches of the evolutionary tree at the bottom of the screen.

Tips:

The “i” icons are the orange and white circles with the letter “i” in the center.
Navigate through the evolutionary tree by pressing on rows in the Tree Navigation window or by pressing the arrows in the main window.
