Do you think the two species from the Do Now have a common ancestor? Explain
CFS:
student describes the relationship between anatomical similarities and differences in animal species
student describes the chronological difference between animal species with a common ancestor

Annotate the following Image

What are the descendants in this diagram? (list)

What body structures did the common ancestor have? (list)

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.
