Seeing that there is so much B/S about the evolution of fish, I have asked a scientist friend of mine to do a basic tree of evolution. will post soon

Hey Korrie,
I'd be very keen to see this please ...
... providing he Czech'ed his facts
(seriously, would love to see it when you get it)

If it reads anything like this please ask your friend to translate it into English.
Class Agnatha or Cephalaspidomorphi, the jawless fishes
Subclass (or order) Cyclostomata, the lampreys and hagfishes.
(In certain classifications, the lampreys and hagfishes are each considered separate superclasses: Cephalaspidomorphi and Pteraspidomorphi, respectively.)
Class Chondrichthyes, the cartilaginous-skeleton fishes
Subclass Holocephali, the chimaeras, or ratfishes
Subclass Elasmobranchii, the sharks, skates, and rays
Class Osteichthyes, the bony fishes
Subclass (or order) Crossopterygii, the coelacanth
Subclass (or order) Dipnoi or Dipneusti, the lungfishes
(In some classifications, the above two subclasses are treated as orders of a single subclass, the Choanichthyes or Sarcopterygii, the lobe-finned fishes.)
Subclass Actinopterygii, the ray-finned fishes
Infraclass (or superorder) Chondrostei, the primitive ray-finned bony fishes: sturgeons, paddlefish, and bichirs
(In some classifications, the bichirs are placed in a subclass of their own, the Brachiopterygii.)
Infraclass (or superorder) Holostei or Neopterygii, the intermediate ray-finned fishes: gars and the bowfin
(In certain classifications, the gars are treated as a separate superorder, the Ginglymodi. The term Ginglymodi also has been used to designate the gars as an order, but this term has been replaced at the ordinal level by the term Lepisosteiformes; orders are now indicated by the ending -formes.)
Infraclass (or superorder) Teleostei or Neopterygii, the advanced bony fishes: herring, salmon, perch.
I think no innocent species of wit or pleasantry should be suppressed; and that a good pun may be admitted among the smaller excellencies of lively conversation.

I'm afraid a "scientist" isn't good enough. You should be looking for a fish taxonomist or geneticist. And you can just put one together, as alot has to do with comparisons of DNA sequences of various fish species. Only based on this can a phylogenetic tree be constructed. Quite a bit of work.
Unless of course such a tree already exists and he's just passing it on to you.
