BIOL 1202 : Exam Two
Document Summary
Phylogeny: the evolutionary history of a species or group of related species. Systematics: 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. Hierarchical classification: linnaeus also introduced the system for grouping species in increasingly broad categories, keep pipes clean of gas. Linking classification & phylogeny: systematists depict evolutionary relationships in branching phylogenetic trees, each branch point (node) represents the divergence of two species, deeper branch points represent greater amounts of divergence, lines represent lineages. Which of the following represents the correct order of taxa, from the most inclusive to the least inclusive: domain, kingdom, phylum, class, order, family genus. Concept 26. 3: phylogenies are inferred from morphological and molecular data. Is the similarity between the australian mole and the north american mole due to homology: no, they are similar due to convergent evolution.
