B-5.5: Exemplify scientific evidence in the fields of anatomy, embryology, biochemistry, and paleontology that underlies the theory of biological evolution.. B-5.6: Summarize ways that scientists use data from a variety of sources to investigate and critically analyze aspects of evolutionary theory.. Spring . 2014. Outline. Review of land plant phylogeny. Characters of seed plants. Gymnosperm phylogeny & diversity. Cycads. Gingko. Conifers. Gnetophytes. Review of land plant phylogeny. Green plants (viridophytes). Phylogeny. The evolutionary history of a species or group of species. . Convergent Evolution. A process in which species from different evolutionary branches may come to resemble each other if they live in similar environments and natural selection favored similar adaptions.. 26.1. Phylogeny. Evolutionary history of a species or a group of related species. Made by using evidence from systematics. Focuses on classifying organisms & relationships. Uses fossils, morphology, genes, & molecular evidence.

Joseph Felsenstein. Excellent reference. What is a phylogeny?. Different Representations. Cladogram - branching pattern only. Phylogram - branch lengths are estimated and drawn proportional to the amount of change along the branch. Section 1.3. Learning Goals. We are exploring modern classification of species using phylogeny.. We are learning to use phylogenetic trees to identify common ancestors.. Modern Taxonomy. traditional classification grouped species according to morphology (body, shape, size and other structural features) . Objective. SWBAT explain and demonstrate that organisms share many conserved core processes and features that evolved and are widely distributed among organisms today.. Agenda. Chapter 25 Quiz.
