Biochemical and molecular systematicserse, both in theory and in the operational aspects of gathering and handling data. A broad distinction should be made between the systematic studies of (a) the different classes of micromolecules or chemical phenotypes and (b) macromolecules which are more or less close to the core of hereditary in

The speciesn biology and philosophy of science have contributed substantially to the debate. The literature concerning the theoretical and operational aspects of the species problem, as well as the related field of speciation mechanisms, has grown to an enormous size. Important monographs published during the

By comparison, Gaston and May say 588 tax-onomists are working in Australia today. I estimate that there are 20 000–30 000 systematists working all over the world today. It is difficult to

The inventory of natural diversityked such questions, especially in these years of growing sensibility towards the tremendous decrease of biological diversity experienced on earth. Obtaining an estimate of existing diversity is a necessary step towards understanding the amount and value of the natural wealth we are currently destroy

Some dangerous trends, and a hope for the future methods. Unfortunately, there is often a hiatus between the theoreticians who discuss the nature of species and homology, and the specialists working on a given group of animals, plants, or fungi. The gap between the frontiers of pure research and the application of principles is still very large,
