Names in taxonomy have seven different and important properties, some due to their existence in the context of classifications. Names confer or facilitate individuation, information storage and retrieval, and set theories of relationships, explanatory power, testable predictions, conceptual power, and language. No other way of naming in science is so powerful. And this is possible because taxonomic naming is done with full consideration of the theoretical specification of empirical data (characters) and their correspondence among taxa via homology statements. Since Darwin and Hennig, sets of homologous characters distributed among taxa allow precise hypotheses of a genealogical relationship, and this relationship is reflected in the way naming results in a classification.
