1. Station 1- Whale Fossil Record
Whale fossils
1.Use the pictures provided: put
The whales in order from newest to
oldest pictures. (Best guess!) A B E C F D

2. Station One - Diagram Two:
7. When you look at a fossil record, how do you determine oldest to most recent organisms?
8. What are some possible environmental conditions that lead to the evolution from a fish to the amphibian?

3. Station Two: Frogs on different islands have different coloring
Station Two: Frogs on different islands have different coloring. Use that information and this picture to answer A and B.

4. Station Three- Homologous Structure
Homologous body structures: structures that are built the same but may be used differently
Image B and G need to be put in the drive

5. Station Three: Image B

6. Consider Function Versus Structure
Station Three Image G.
Consider Function Versus Structure
(These species are not closely related.)

7. Station Four- Vestigial Structures
What is the vestigial structure in a Bottlenose
Dolphin and what was it originally used for?
The tail bone (coccyx) in humans
is a vestigial structure.

9. Station Six A- DNA Analysis
A. Looking at the big cat diagram (on the next slide) which two cats are most closely related (Hint: compare the codon sequences)
Cheetah: ATC CGC TGA TTA TTT TCA ACT AAT CAT AAA GAT ATC GGT ACT CTT TAC CTC CTG
Leopard: AAC CGC TGA CTA TTT TCA ACC AAT CAC AAA GAT ATT GGA ACT CTT TAC CTT CTA
Tiger: AAC CGC TGA CTA TTT TCA ACC AAT CAC AAG GAT ATT GGA ACT CTT TAC CTT TTA

Big Cat Diagram

11. Station Six B- DNA Analysis: go to back counter
Place the animals on the cladogram from the most closely related to the shark down to the dolphin. (Hint: the organisms that are the most closely related have the most letters or codons in common)
Use the DNA Sequence Cards provided at your table to put the organisms in the correct order.
Shark
Camel
Dolphin
