Document Summary
Test 2: chapter 26 phylogeny and the tree of life: phylogeny: the evolutionary history of a species or group of related species, systematic: an analytical approach to understanding the diversity and relationships of organisms. Concept 26. 1: phylogenies show evolutionary relationships: taxonomy: the ordered division of organisms into categories based on a set of characteristics used to assess similarities and differences, ex: librarian categorizing books. Hierarchial classification: linnaeus alo introduced the system for grouping species in increasingly broad categories, keep pipes clean of gas, kinky people come over for great sex. Classification: kingdom- animalia, phylum- chordata, class- mammalia, order- primates, family- hominidae, genus- homo, species- h. sapiens. Linking classification & phylogeny: systematists depict evolutionary relationships in branching phylogenetic trees, each branch point (node) represents the divergence of 2 species, deeper branch points represent greater amounts of divergence, lines represent lineages, figure 26. 4. Concept 26. 2: phylogenies are inferred from morphological and molecular data.
