Chapter 5 - Getting Ahead
- Why are the trigeminal and facial
cranial nerves both complicated and strange in the human body?
- List the structures that are formed from the four
embryonic arches (gill arches) during human development.
- What are Hox genes and why are they so
important?
- Amphioxus is a small invertebrate yet is
an important specimen for study –why?
Chapter 6 - The Best Laid
(Body) Plans
- Early embryonic experiments in the 1800s
led to the discovery of three germ layers. List their names and the organs
that form from each.
- Describe the blastocyst stage in
embryonic development.
- What is meant by “ontogeny recapitulates

- Refer to the timeline on p.121 – what is

- What is the most common protein found in
the human body? Name it and describe it.
- Explain how cells “stick” to one
another; give one example.
- How do cells communicate with one
another?
- What are choanoflagellates and why have
they been studied by biologists?
- What are some of the reasons that
“bodies” might have developed in the first place?
Chapter 8 - Making Scents
- Briefly explain how we perceive a smell
- Jawless fish have a very few number of
odor genes while mammals have a much larger number. Why does this make
sense and how is it possible?
