Document Summary
Large-scale changes at or above the special level. Associated with research on the formation of new taxonomic groups. Modified typological species concept: similar-looking individuals that can successfully produce fertile offspring lumped into discrete species categories. (how in early taxonomy linneaus classification typological way) Must apply all known morphological, behavioural, and ecological data to use as deductive proof of reproductive isolation between species. Species concept all have underlying themes divided into. Bio species concept species are actually interbreeding pop. When pop not able to interbreeding pop is reproductively isolated (most important for bio species concept) Not geographic iso but reproductively iso (continuum) Eg. iso starts w/ recognition of potential mate. Problems w/ bio species concept: potentially interbreeding is hard to identify. Can"t observe fossil reproduction don"t know if potentially interbreeding. Smallest aggregation of sexual populations diagnosable by unique combination of character states. Measure and analyze variation in characters within and between populations. Can be applied to living and fossil organisms.
