Sorry, but this is not clear. What happened to 4? What does B represent? And your example with Proteobacteracea
doesnt help, because I dont know what branching pattern you are intending to represent. Let us keep this simple
and use an example that everyone is familiar with. The relationships of extant Amniota are (in cladistic indented
form);
Amniota
Reptiles
Turtles
Saurids
Lepidosaurs
Archosaurs
Crocs
Birds
Mammals
Monotremes
Therians
Marsupials
Placentals
How would you represent this in your classification system? No need to use fancy latin names; I just want to see the
logic of the representation.
