EVOLUTION EVIDENCE

Hypothesize which embryo is from each of the following organisms: Human, Chicken, Rabbit, Tortoise, Salamander, Fish.

Hypothesize which embryo is from each of the following organisms: Human, Chicken, Rabbit, Tortoise.

Describe how the embryos changed for each of these organisms from their earliest to latest stages.

Look again at the six embryos in their earliest stages. Describe the patterns you see. What physical similarities exist between each of the embryos?

Does this suggest an evolutionary relationship? Explain how these embryos can be used as evidence of a common ancestor between each of these six organisms.

For each animal, indicate what type of movement each limb is responsible for. What is the primary function of the whale's limb?

Compare the skeletal structure of each limb to the human arm. Relate the differences you see in form to the differences in function for the following animals: Cat, Bat, Bird, Crocodile.

Compare the anatomy of the butterfly and bird wing below.

What is the function of each of these structures?

How are they different in form? Give specific differences.
