Popis:	Biogeography, as a topic for discourse or discussion, is in some ways like religion: both topics lend themselves to ever more complicated treatment in the abstract, which is apt to border even on the miraculous, but whichis apt to crumble in confrontation with concrete facts of life. Nelson and Platnick (1981:375) Having failed to dissect these concepts (center of origin, vicariance) to their core, contemporary zoogeographers founder in a self-created morass of chance hops; great capacities for, or mysterious means of, dispersal; rare accidents of over-sea transportation; small probabilities that with time become certainties; and other pseudo-explanations.
