If they can breed, wouldn't they technically be races or breeds and not species?
Posted by littlebeast
Only if the offspring is fertile (by the traditional Linnaean definition - modern phylogenetics may have provided more precise definitions of speciation). A case where one of the two possible pairings results in a fertile crossbreed while the other combination yields a crossbreed that uniformly dies before it reaches reproductive age is borderline. Whether you would call them separate species or not depends on how much you need to pad your publication record :-P
