Document Summary
Chapter 26: phylogeny and the tree of life. Concept 26. 1: phylogenies show evolutionary relationships: explain the following characteristics of the linaean system of classification, binomial nomenclature, 2 part scientific name (genus species, hierarchical classification, shows what ancestor came before. Each branch, or node, represents the divergence of two species with the deeper branches showing greater divergence from original ancestor: lines of tree show lineage. Explain some of the problems that systematists may face in carrying out molecular comparisons of nucleic acids. Concept 26. 3: shared characters are used to construct phylogenetic trees: define a clade. Concept 26. 4: an organism"s evolutionary history is documented in its genome: distinguish between orthologous genes and paralogous genes. Concept 27. 2: rapid reproduction, mutation, and genetic recombination promote genetic diversity in prokaryotes. List three factors that give rise to high levels of genetic diversity in prokaryotes: rapid reproduction, mutation genetic recombination, describe three processes that produce recombinant dna in prokaryotes.
