Compared to the Linnaean system of classification, what is the advantage of classifying species into clades? A. Clades show evolutionary relationships. B. Clades identify domains and kingdoms. C. Clades group single-celled organisms separately from multicellular organisms. D. Clades include more species.

A. Clades show evolutionary relationships

Explanation:

Linnaean system is a system of classification that classifies every organism into a kingdom, phylum, class, order, family, genus, and species. This system was created in that time when scientists have no understanding about the evolution of organisms. So this system is not based on the evolutionary relationships among different organisms.

On the other hand in phylogenetic system of classification the organisms are grouped into clades. A clade is a group of organisms that have been descended from a common ancestor. So, clades show the evolutionary relations and thus these are better than Linnaean system.
