Ref for biological species and genus
Sorry for the ignorant question. I am looking for the definitive
reference for the the biological species concept (a population capable
of interbreeding to produce fertile offspring). I understand that
this notion has been extended to define a "biological genus" as a
population capable of interbreeding to produce live offspring that may
not be capable of reproducing further -- is there a reference for
this, too? Many thanks.
