Document Summary
Species: a population of organisms capable of interbreeding and producing fertile offspring. One species should be genetically diff from another species: this defi(cid:374)itio(cid:374) (cid:272)a(cid:374)"t (cid:271)e applied to organisms that reproduce asexually or those like da(cid:396)(cid:449)i(cid:374)"s fi(cid:374)(cid:272)hes, (cid:449)hi(cid:272)h h(cid:455)(cid:271)(cid:396)idize. Thus, the working definition of species depends on the organisms to which it is applied. Hybridization: when 2 species interbreed and produce fertile offspring. Variation in reproductive patterns complicates the application of the species concept, like hybridization. Carlous linnaeous (swedish naturalist) 1st modern practitioner of taxonomy, which is the science of the classification of organisms into an ordered system that indicates natural relationships. In other words, the science that identifies, names, and classifies new species. Is never used without the full/abbreviated generic name preceding it b/c the same species name is often given to species in diff genera. 1st letter of the name = always capitalized. Whole name = always italicized (or underlined in handwritten work)
