Construct a table listing the important characteristics of Branchiostoma (Amphioxus), Petromyzon (Lamprey), Squalus (Dogfish), Perca (Perch), Necturus (Mudpuppy) and Lithobates (Bullfrog) to construct a cladogram.
PLEASE construct a cladogram with these 6 generas. This is really important.
Also, indicate which characters might be plesiomorphic (generalized for some or all of these taxa) and which might be apomorphic (derived) for each of the taxa.
Branchiostoma (Amphioxus) |
One of the few living genera of lancelets (order Amphioxiformes) Fossil dated back to cambrian period or precambriam |
Petromyzon (Lamprey) |
Ancient extant lineage of jawless fish of the order Petromyzontiformes Fossils dates back at least 360 million years ago |
Squalus (Dogfish) | Squalus acanthias fossils date back to the Miocene 11 MYA |
Perca (Perch) | Fossils dates back to 12,000 to 10,000 year old; end of ice ages |
Necturus (Mudpuppy) | Fossils found of Paleocene and Pleistocene era |
Lithobates (Bullfrog) | Fossils are known from the Pleistocene (Illinoinan–Sangamonian glacial age) |
Cladogram for given generas:
Plesiomorphic: A pineal-parapineal apparatus in Branchiostoma
Apomorphic: A caudal peduncle with lateral keels and the caudal fin is without a subterminal notch are example of apomorphic character of squalus

Consider the anatomy of the following six genera: Branchiostomata (Amphioxus), Petromyzon (Lamprey), Squalus (Dogfish), Perca (Perch), Necturus (Mudpuppy) and Lithobates (Bullfrog). Recall that you had the opportunity to study these animals in the laboratory portion of this course. Construct a table listing the important characters of each of these six genera that you think would be useful in constructing a cladogram or phylogenetic tree. Indicate which characters might be plesiomorphic (generalized for some or all of these taxa) and which...
Looking at the antomy of: Bufffrog, Amphioxus, Lamprey, Perch, Dogfish and MudPuppy i) List the characters of each organism listed above that will help in building a phylogenetic tree. ii) Depict which characteristics that will be plesiomorphic and which will be apomorphic. iii) From the information above, make a phylogenetic tree that illustrates the assumed relationship (phylogenetic) of the chordates listed above. iv) In the form of an essay, utilize the anatomy of the six organisms above, justify your phylogenetic...
