Comparative Anatomy - Extra Practice
Compare the anatomy of the butterfly and bird wing below.
1. What is the function of each of these structures?
2. How are they different in form? Give specific differences.
Compare the overall body structure of the cave fish and the minnow below.
1. What is the biggest, most obvious difference between the body structures of these two fish?
2. Assume the two fish came from the same original ancestor. Why might the cave fish have evolved without eyesight?
3. What kind of sensory adaptation would you hypothesize the cave fish has to allow it to navigate in a cave, including catching and eating food?
