As this thread seemed to have enlighted, particularly with Tindall's nice
post about calssic definitions, there is no "phenetic character".
I wonder how one can have a "phenetic data matrix".

We very certainly won't be able to move on (together) if we have such deep
disagreement about what the words we use mean.
My definition of "phenetic" is Tindall's one : it qualifies a way of
treating the data, i.e. grouping on the basis of overall similarity between
taxa. Thus, an analysis cannot be phenetic "because of the data matrix".
Definitions matter for real debate.
