Perhaps distinguish. That's actually the easy part,
and is a lot to do with why cladistics has caught on
so well. In groups of organizisms where the forms
mimic and assume characteristics of each other, such
as bacteria and genes, this is a lot more difficult. A
system for grouping genes and bacteria will not work
the same because so-called higher organisms will not
have the mutability that bacteria and such show.
Defining things requires concrete definitions to
cease confusion. The fact that listing taxa and
placing markers beside them suggests that a definition
is ambiguous, rather than considered true, based on a
ambivalence on whether or not a group might exist.
