Above are the bones of two imaginary species. Look at the body structures for both species, then select which body structures these two species share.

[Skull, Backbone, Tail, Front limb, Back limb]

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

Complete the guides notes below

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.
