Unformatted text preview: 1 After this slide presentation: Be able to observe a phylogenetic tree and discuss the relatedness of organisms included. Begin to understand how the relationships are developed from the data. Discriminate between homologous and analogous traits. Understand their use in building a phylogenetic hypothesis. Understand why, based on complexity, different traits are given different priority in constructing trees. Recognize the shortest tree. Know the order of the binomial nomenclature and the “names” for humans Identify the taxa (plural of taxon) represented in a phylogenetic tree. 2 Taxonomy and Phylogeny C. Hierarchical classification and Binomial nomenclature I. Constructing the trees A. Grouping by shared derived characters B. Homologous vs Analogous characters II. Molecular evolution: How DNA evolves A. review the genetic code and locus structure B. Patterns of mutation accumulation: fast genes and slow genes 3 Taxonomy / Phylogeny Why do we show you these trees when we discuss biodiversity? 4 Taxonomy / Phylogeny They illustrate the hypothesis of the common ancestor shared by the organisms 5 all dead all living All individuals above a node share a common ancestor share a trait(s) from the common ancestor Common ancestor Common ancestor Common ancestor Basics of the phylogenetic hypothesis 1....
