Document Summary
19. 1a naming species: taxonomy: the science of classification of organisms into an ordered system that indicates natural relationships (carl linnaeus) 19. 1b binomial nomenclature: binomial nomenclature: the naming of species with a two part scientific name, first indicating the genus taxonomic category ranking (dkpcofgs, second indicating the species, specific epithet: species name in a binomial, first letter capitalized. Domain, kingdom, phylum, class, order, family, genus, species (darling king phillip came over from germany swimming) Good to look at closely related species (minor details) Bad to look at to identify ancestor (independent evolution, molecular similarities hard to distinguish if from ancestor: however, does not apply to asexually producing species, cannot study extinct organisms no data on reproductive habits. Summary: look at cohesiveness of species and emphasizes genetic distinctness. One of the requirements of biological species definition. Reproductive isolating mechanism: a biological characteristic that prevents the gene pools of two species from mixing.
