Abstract

related species, which completely neglect within- distances are not always a good guide for species species population differentiation and are content with classification, they do reflect the young age of these one or a few specimens of each species. Nevertheless, species flocks. It would thus be difficult to compare more than other methods, molecular markers have the biodiversity of 300 closely related cichlid species shown that there is often little discontinuity between from Lake Victoria with that of 300 divergent species genetic population differentiation and species diver- in a rainforest area, and to set conservation prior- gence (Avise, 1994), implying that sometimes species ities accordingly. The current trend to use evolutionary may be artificial units. Thus molecular markers may significant units (ESUs) for conservation purposes in well have helped to pinpoint the futility of species North America (Waples, 1995) reflects an appreciation concept discussions, which, after more than two of such concerns at the intraspecific level. centuries, have failed to result in a consensus and are unlikely todosoin the near future.
