Phylogeny- the evolutionary history of a species or group of related species. Systematics- an analytical approach to understanding the diversity and relationships of organism. 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. Binomial nomenclature- carolus linnaeus: 2 part format of the scientific name of an organism, genus and species, written in different form: italics, genus always capitalized; species lowercase, homo sapiens. Hierarchical classification: grouping species in increasingly broad categories, keep pipes clean of gas, kindly professors cannot often fail good students, most inclusive least inclusive, domain, kingdom, phylum, class, order, family, genus, species, eukarya, animalia, chordata, mammalia, primates, hominidae, 26. 2 phylogenies are inferred from morphological and molecular data. Shared ancestry: clicker- is the similarity bw the australian mole and the north. American mole due to homology?_____ no, due to convergent evolution. 26. 3: shared characters are used to construct phylogenetic trees.
