We argue here that of these three concepts of species, the traditional, morphological one is still the best. The morphological species, we will show, is the external manifestation of the symbiogenetic species. The assignment of similar animals of compatible genders to the same species if, in their natural habitat, they can mate and produce viable offspring is adequate for mammals and many other animals but it is not general. Here we widen the concept of speciation to include all organisms. Our symbiogenetic definition of species is as follows.
