Why do paleontologists make diagrams (evolutionary trees) like this? What are they trying to show?CFS:- student describes the benefit of using models and graphics

Why do paleontologists make diagrams (evolutionary trees) like this? What are they trying to show?
CFS:
- student describes the benefit of using models and graphics
- student describes the chronological difference between animal species with a common ancestor
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.
