questions can be resolved through a cladogram including E. coli,
Sophophora melanogaster, zebra fish, mouse, human, and the taxon under

No, actually, it gets yet better, when *S. melanogaster* is treated as

chanterelles than to bean rust.
And there's the Nature paper on the ancestral vertebrate karyotype
which reconstructs the ancestral _osteichthyan_ karyotype... and says
"tetrapod" when it means "sarcopterygian" (not "tetrapodomorph";
