Consider the following animals:
Earthworm
Flatworm.
Frog.
Jellyfish.
Lamprey.
Tuna.
Create a table of fundamental traits for these six animals as a basis for building a cladogram. Use traits that are either present or absent in a given organism. Use the jellyfish as an outgroup and construct a cladogram that accurately depicts the branching of the evolutionary lines of descent of these animals.
Where do I even start creating a cladogram? I know what it is, but my book nor anyone can explain where I start.
