1. Build a cladogram (phylogeny or
phylogenetic tree) of the group of
frogs using the following
characters:
• claws, chin hair, horn, tail,
spikes, digits, spots,
tympanum, lateral fold,
nostril
• Start by making a character matrix
in your lab report.
• Based on the characters and
pictures of the frogs, fill out the
character matrix for all seven
species (A-F and the outgroup).
