Cladistics-This way (method) groups all the descendants from a common radiation into a clade as a related group and no others. Phylogeny - is a way of tracking evolutionary relationships based on shared characters between different species

Explanation:

Cladistics is concerned with entire branchings. This way (method) groups all the descendants from a common radiation into a clade as a related group and no others. The clades are monophyletic.

Cladistics is a narrower definition of an older, less precise concept now days.

Phylogeny is a way of tracking evolutionary relationships based on shared characters between different species ... This method allows convergent characters to be grouped despite their having followed a separate evolutionary path.

Cladistics is a way (method) of grouping the related branches based on sharing derived characters within the group. However, these characters are not found in any other species except by convergence.
