I've tried to run this stuff through PAUP. My problem is that I don't
trust most of the traits available in the literature, and don't know
enough about dental anatomy. For example, in the description of A.
anamensis, we see such traits as "mesiobuccally expanded trigonids" --
well, compared to what? Has this been quantified in any way? etc. etc.
Similarly, some traits are well known for some taxa, but have never been
examined in others, or are assumed based on what we already "know" to be
present or absent in other taxa.
In other words, a hardcore cladistic analysis of hominoids needs doing.
You might check out H. Erwin's database. He's put a lot of work into it.
