I have a thought regarding this subject from the nontaxonomists point of view. I have always been under the impression that taxonomy was not only to catalog the organisms of the earth but to better facilitate communication among the different groups of scientists (and nonscientists). We've already come to a point where in many cases an organism cannot be identified morphologically unless it's specific origin is known (which is something else I don't understand). I can imagine the number of species identified on the basis of DNA alone... it would be a nightmare. I can see where it could be useful in supporting the idea of a new or existing species. Ed Pirog
