Taxon

Conceptual entity which is supposed to group together all living organisms that have certain well-defined taxonomic or diagnostic traits in common. The species constitutes the basic taxon for systematic classification. The higher the rank of the taxon the greater the degree of resemblance (the number of characteristics they have in common) between the individuals concerned (plants, animals, mushrooms, bacteria, chromista) is low, and vice versa.
