Evolution Cladistics Labs
Classifying with Cladistics: Part II
Now that you have mastered cladistics, a method that University level scientists do everyday, you are ready to use cladistics to determine how the following organisms are related. Put a plus(+) if the animal has the feature, a negative (-) if the animal does not have the feature, and a question mark (?) if you and other do not know if the animal has the feature. You do not need to fill in the dark grey boxes. Examine the photos carefully!
