Chapter 23: Evolutionary Patterns: Phylogenies and Fossils Your Name : Section 23.1 Reading a Phylogenetic Tree Close your books/notes: Connect the new information in this section with what you knew before you read this section. 1. Describe information that is new for you in section 23.1 I learned that the order of the branches in a phylogenetic tree shows you the order of what happens throughout time. I also learned that sister groups are more closely related than any other group. 2. How do the new ideas work with what you already know? Before reading this section, I already knew what a phylogenetic tree was and that they showed the relationships between different species. I also knew that every species has a common ancestor. 3. Explain how your prior knowledge and these new ideas work together. Provide an example. Use specific and concrete examples Be sure to make a link between the idea and the example. My prior knowledge and these new ideas work together as sister groups are part of the phylogenetic tree and even though a sister group shares a common ancestor, they are still more closely related to each other than their common ancestor. 4. List two “I wonder (if, whether, why, how, which, where, who, etc.) . . .” questions that you have as a result of reading this section. I wonder why phylogenetic trees are organized the way they are. I wonder how researchers determine where to organize certain species into the phylogenetic tree. 5. Indicate how well you have learned the material in this section. Choose from the options below:

    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.
