1. Station 1- Fossil Record Diagram 2
Whale fossils
1.Use the fossils provided: put
them in order from youngest to
oldest fossils.

2. Station One- Fossil Record: Diagram 2

3. Station Two

4. Station Three- Homologous Structure
The colors represent the same bones
In the different vertebrates, which
Suggests we all came from a
Common Ancestor.
Use the images provided to answer
the questions.
Image B and G need to be put in the drive

5. B: Consider Function Versus Structure (These species are closely related)

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

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

11. Station Six B- DNA Analysis
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.
