I agree with the point OP raises. For instance, there will never be two brontosaurus skeletons found from the same species again. With brontosauruses they say, "Because these two skeletons are not the same, these are two different species." Obviously this is just an insurance policy on the funding of whomever is studying which brontosaurus skeleton. However, if you used the same criterion for dogs then then would be 30 distinct species of German shepherds. If you applied the brontosaurus standard to humans, father would be classified as a different species than their sons.
