Most are. But among the living there are more possibilities to test this --
we can take the morphospecies concept into the genetic realm (which
regularly results in surprises -- now we have 2 species each of African
elephant, gorilla and orang-utan), we can use the biospecies concept, along
with many others such as ecospecies. Many recent (bio)species are impossible
to tell apart from their skeletons. We probably can't detect a fossil ring
species. And so on.
