It seems a shame that less than 1 percent of all the species that ever lived survive today and that only about 5 percent of the sum of the world's living species have names. Yet, our preservation efforts must be built on a solid foundation: an ordered taxonomy of living species. So we are forced to do as politicians do--compromise and move forward--often before all the required data are at hand. Every good scientist I know finds such an exercise counterintuitive, difficult, and sometimes impossible. But the really good ones try anyway.
