Compared to the linnaean system of classification, what is the advantage of classifying species into clades?

clades show the evolutionary relationships between species.

Explanation:

A clade is a term that is defined as organisms that share a derived character from a group that includes the most common ancestor and its descendants. Cladistics is a type of classification that is based upon phylogeny but does not show the historical event, and has no time scale. It is strictly monophyletic, and it produces a cladogram which shows all the evolutionary relationships among species and the evolutionary lineages split from common ancestors. The Linnaean classification system focuses on the physical traits of species, has a time scale.  

i'd say that the moon rock is about 2.2 billion years old.

i think that it is c, d, and e, hope this
