Document Summary

also reproductively incompatible: the point at which daughter populations can be considered a different species depends how you define distinct species, species=different kinds, defined in different ways, morphological species concept: members look alike because they share alleles. use binomial system of nomenclature but we need something else because some males and females of the same species look alike and sometimes parents and offspring of same species do/don"t look alike: biology species concept: species are groups of actively or potentially interbreeding natural populations which are reproductively isolated from other such groups. Individuals in a population can mate with each other but not with those of another population. they are a distinct evolutionary unit within which genes recombine. first level daughter populations are morphologically distinct, second level populations are morphologically and biologically distinct www. notesolution. com. when populations are separated by a physical barrier=geographic speciation: thought to be dominant mode of speciation.
