Biology of the Vertebrates Study Questions

Note: These study questions are not necessarily comprehensive, nor are they meant to be. They are meant to supplement your lecture notes as you review them, and alert you to the ways in which you should be thinking about the material, and formulate questions to test yourself. Exams will NOT be limited to the material highlighted in these questions, or their formats, so your lecture notes should be your primary reference.

Lecture 1

1. List and describe 3 applications for the study of vertebrate biology, and be sure to provide examples.

2. Which major taxonomic group of vertebrates is the most speciose? The least? What might account for these differences in numbers of species? Roughly what fraction of animals do vertebrates comprise?

3. What is “cladistics”? Define “monophyly,” and describe how this differs from “paraphyly.”

4. Define “synapomorphy” and “plesiomorphy.” Explain how a synapomorphy at one level can be plesiomorphic at another (or vice-versa). Briefly explain how it is that we (humans) are considered ‘bony fish’.

5. Where do vertebrates fit in the larger scheme of organisms?
