BIS2C Winter 2011 1 BIS2C Study Guide: Metazoans Trees as road maps Be familiar with the phylogenetic relationships of the major clades of animals, and the distribution of characters on the tree. Practice drawing trees in which you label both taxa and traits. In your textbook ( Life , 9 th edition) the following are useful summary trees: Figures 31.1, 32.1, and 33.1. If you have the 8 th edition be sure to check the relevant figure from the 9 th edition (available on the lecture PowerPoint slides) because the trees have changed between the two editions. With respect to Figure 31.1 (overview of relationships among major animal groups) be aware of how recent molecular phylogenetic studies have changed this picture. Take the characteristics of each major group of animals (with respect to body form, presence/absence of gut, nervous system, reproduction, etc.) and summarize this information in a taxon by character matrix. Then plot the characters on a tree (or trees).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
