Objective: SWBAT evaluate the placement of  species on evolutionary tree by using digital models.

Do Now:

Where should Species C be placed on the tree?

0

What is one body structure you used to make your decision?

Exit Ticket Review: 

Exemplar: 
"Species C and E are most closely related because they have a most recent common ancestor and also because they have similar body parts like a skull, the backbone,and the legs."

Approaching: 
"The species C,E are most closely related because they have the same new structure"

Guided Notes: 

Guided Notes: 

Do:
• Open Cetaceans mode  of the Sim, press TREE to open Tree View, and navigate to the Cetaceans branch of the tree.
• Study the Blue Whale and Orca structures.
• Read the first question below and place a fossil species into Location 1 (see image above), then repeat this for each of the locations.
• For each location, choose between the two possible species given in the question.

Tip:
• Use the Structures tab in the Study windows and the “i” icons to help you make your decisions.



TIP 2:
Animals that look most similar to the Whale and Orca will be located closer to them on the evolutionary tree.
Animals that look most most different to the Whale and Orca will be located farther  to them on the evolutionary tree.

Practice:

• For each location, choose between the possible species given in the question.

HINT:
Animals that look most similar to the Whale and Orca will be located closer to them on the evolutionary tree.
Animals that look most most different to the Whale and Orca will be located farther to them on the evolutionary tree.

Which species is Dorudon more closely related to: the blue whale or Ambulocetus? Which diagnostic structure(s) could you use to show this?
CFS:
student describes the relationship between anatomical similarities and differences in animal species
student describes the environmental difference between animal species with a common ancestor based on body structures
"I think that the Dorudon is mores closely related to the ... because ..."

(THINK: Does the Dorudon have more similaries to the whale or Ambulocetus)
