The biological species concept defines organisms as being, or not being, of the same species based on whether they can interbreed to make fertile offspring. Since all naturalistic models require more than one speciation mode, and since the only way to reconcile phylogenetics and paleontology is to posit just one speciation mode, something other than strictly natural processes must operate.
