Chapter 19 & 26. 1: classification, species - unit of classification/ type of organism a. i. Taxonomy groups a. i. 1. a. i. 2. a. i. 3. a. i. 4. a. i. 5. a. i. 6. a. i. 7. a. i. 8. Given names of taxonomy via binomial nomenclature a. ii. 1. Specific epithet not capitalized; is not unique: classification (fig 26. 3) b. i. Arranging in such a way evolutionary relationships can be understood b. i. 1. Phylogeny evolutionary history of group of species b. iii. End result: classification schemes represent a hierarchical classification (various levels nested within levels above it: phylogenetic trees (fig 26. 4, 26. 5) c. i. Branching diagram represents evolutionary history of a particular group of organisms c. i. 1. Shoes patterns of descent, not phenotypic similarity c. ii. Series of dichotimies (two way branching points) c. iv. Branch points at which lineages split; divergence c. iv. 2. from common ancestor. Groups of organisms that share an immediate c. iv. 3. common ancestor; each other"s closest relative. Has one branch point that represents most recent c. iv. 4. common ancestor and all taxa on tree.
