The core meaning of "taxon" is a formally defined group in a biological classification system. It is an abstract, conceptual category used for organizing and communicating about the diversity of life. The reference to "natural relations" in some definitions emphasizes that modern taxonomy aims to group organisms based on evolutionary relationships (phylogeny), not just superficial similarities.
