Towards the systemhat this distinction rests largely on tradition, rather than on sound theoretical reasons. However, it is true that, until recently, people interested in macrotaxonomy and people interested in microtaxonomy have been different.

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.
