Chapter 26 – Phylogeny and the Tree of Life Phylogeny How are phylogeny and systematics related? Based on the figure to the right, list all of the information you can about this phylogeny (e.i. time, relationships) What is the difference between taxonomy and systematics? Hierarchical Classification – refer to the “Naming the Panda” document Linking Classification and Phylogeny What is a phylogenetic tree? What errors might occur when composing a phylogenetic tree? What is used to ultimately determine their “closeness”? What is the shortcoming of the Linnaean classification system? What Can I Learn From a Phylogenetic Tree? – Read the following scenarios and determine if a phylogenetic tree would be able to determine such information. Explain your answers. 1. The tiger and the lion have developed from the same ancestry. The lion has developed a mane in order to attract lionesses, while the tiger has developed stripes in order camouflage in the forests to more swiftly take down its prey without detection. 2. From looking at the lineage at the top of the page, one can deduce that the humans, fungi, and angiosperms all emerged at the same time on the evolutionary clock. 3. We can infer that humans evolved from primates. Concept Check 1. Which levels of the classification system in Figure 26.3 do humans share with leopards?
