Portfolio Activity, Part 1
Five species of Xenite-an imaginary animal-have been found on a planet in another
solar system. Based on the order of the rock layers in which fossils were found, species
A appears to be the oldest and probably the most primitive. There is no evidence to
support the relative age of the other species of Xenite.

Be the evolutionary biologist, and complete the following activities to build a
cladogram of Xenites.
a. spines
b. eyestalks
c. tail
D
d. mouth
1. Create a table noting which species of Xenite has each characteristic below,
marking each as yes or no.
E
2. Study your table, and figure out the order of evolution of each character. You
have been given reason to believe that, based on the fossil record, Xenite A is
the ancestral species. For the Xenites, consider what appear to be homologies
and analogies. Create your cladogram for the Xenites.
