CONCEPT
The Biological Species Concept
Mayr's 1942 definition of species by reproductive isolation rather than morphological similarity — a framework whose structural logic illuminates whether human and artificial intelligence can genuinely merge or remain fundamentally isolated.
Ernst Mayr spent more intellectual energy on the species concept than on any other single problem in biology. His answer — the biological species concept, first articulated in Systematics and the Origin of Species (1942) — defined species not by morphology but by reproductive isolation. A species is a group of actually or potentially interbreeding natural populations, reproductively isolated from other such groups. Members of a species can exchange genetic material; members of different species cannot. The boundary is maintained not by human classification but by biological mechanisms — behavioral isolation, geographic separation, genetic incompatibility — that exist in nature regardless of whether any taxonomist has noticed them. Species, in this framework, are not clusters of similar individuals but reproductive communities whose genetic fates are linked.

The significance extends beyond taxonomy. The biological species concept makes a claim about what kinds of entities species are: they are historical entities connected by the
