Proposal for a standardized temporal scheme of biological classification for extant species

With respect to conveying useful comparative information, current biological classifications are seriously flawed because they fail to (i) standardize criteria for taxonomic ranking and (ii) equilibrate assignments of taxonomic rank across disparate kinds of organisms. In principle, these problems could be rectified by adopting a universal taxonomic yardstick based on absolute dates of the nodes in evolutionary trees. BS using procedures of temporal banding described herein, a simple philosophy of biological classification is proposed that would retain a manageable number of categorical ranks yet apply them in standardized fashion to time-dated phylogenies. The phylogenetic know ledge required for a time-standardized nomenclature arguably mag. emerge in the foreseeable future from,ast increases in multilocus DNA sequence information (coupled with continued attention to phylogeny estimation from traditional systematic data). By someday encapsulating time-dated phylogenies in a familiar Set modified hierarchical ranking scheme, a temporal-banding approach would improve the comparative information content of biological classifications.
