Objective: SWBAT use observations of body structures to make inferences about common ancestors.

Do Now: 

Using careful observation, Describe at least two differences between these two limbs. Start with the hand bones.

(THINK: look at length of bones, shape of hands, etc.)

Exit Ticket Review: 

Guided Model:

Yesterday's Exit Ticket:

Identify the descendants in the evoluntionary tree from yesterday's exit ticket.

Guided Notes: 

Part 1: Observing Species’ Front Limbs Record your careful observations of the zoomed-in illustrations of front limbs for the dire wolf, the fruit bat, and Titanotylopus

Record your observations about the front limb of the dire wolf.

(THINK: are the limb bones long or short? are the foot bones long or short?)

What environment do you think would make the front limb of the dire wolf an adaptive trait.

(THINK: do you think that is a land, water, or air animas-why? why do you think the limb bones are shaped the way they are?)

Practice:

Record your observations about the front limb of the fruit bat.

(THINK: are the limb bones long or short? are the foot bones long or short?)

What environment do you think would make the front limb of the fruit bat an adaptive trait.

(THINK: do you think that is a land, water, or air animas-why? why do you think the limb bones are shaped the way they are?)

Exit Ticket:

Use the text descriptions as well as the images in the Structures Tab to answer the questions below.

What differences do you see between the animals above?

(THINK: use the slides above and the color coded stuctures to help identify similarites and differences)

Why do you think this bone structure was different for each of the species? Make a hypothesis about the environments of the two species as supporting evidence.
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 species have different bone structures even though they may have common ancestor because ... "

(THINK: Why does the Saber Toothed Cat have longer front limbs than the Kutchicetus?

What environmnet is the Saber Toothed Cat best suited for? What environmnet is the Kutchicetus best suited for? )
