Classification Practice
In the exercises that follow, arrange the items listed into different groups. Give each group a
title indicating what the members of that group have in common.
1. German Shepherd, Great Dane, parrot, Irish setter, canary, husky, robin, pigeon

4. Number the following classification groups from the largest to the smallest (the largest
group will be Number 1). Also, define each of the classification groups below.
_____ Class
_____ Genus
_____ Kingdom
_____ Species
_____ Phylum
_____ Order
_____ Family

Cladogram Practice
Step One “The Chart”:
1. First, you need to make a “characteristics chart” the helps you analyze which characteristics each species. Fill in
a “x” for yes it has the trait and “o” for “no” for each of the organisms below.
Backbone
Legs
Hair
Earthworm
Fish
Lizard
Human
“yes count”
Step Two “The Cladogram”:
This step converts the above chart into a cladogram. The traits are written on the main line, and species go on the
branches. On the cladogram below, try to put all the characters and the species in the correct evolutionary history.
2. Complete the following chart the same way as the above example. After you complete the
chart, use it to create a cladogram on the back of this paper.
Hair
Legs
Thumbs
eyes
Human
Snake
Monkey
Mouse
Starfish

Interpreting a Cladogram
First, let’s practice interpreting
some cladograms. Looking at the
images, answer the questions
below
1. Which animals have
mammary glands?
2. What animal does not
have jaws?
3. Which animals have lungs?
4. What other animals would come after the chimp?
5. What could the character trait be that would come after the chimp?
6. What character trait separates salamanders and lizards?
7. Based on the cladogram, which shared a common ancestor most recently: a mouse and a lizard, or
a mouse and a perch?
8. Make a characteristics chart (hint: look at previous page for an example)
