A cladistic approach, attempting to reconstruct phylogeny, is the most objective way of depicting relationships; whole-genome comparisons, such as DNA-DNA hybridisation, show that genetic similarity really does increase with recency of common ancestry. But if we aim to represent taxonomically every dichotomy in the cladogram, more bassed more taxonomic division will be required, and this has led to the current trend towards unranked taxonomies. Key words: Morphological, molecular, cladistics, unranked taxonomies, linking time to taxonomic rank.
