Correction - I use phenetic to refer to overall similarity, whether in
morphology or molecules and cladistics to refer to analysis of the
distribution of derived character states shared between various taxa of
an ingroup.

And with that I could concur.

If you consult many of the

Which would be confusing indeed.
