Cladogram

Build your own cladogram.  

• You should include the characteristics which separate the different groups, the name of the group, and a picture of a representative animal.
• Start with all animals and include branches for porifera, cnidaria, and ctenophora.
• Do this in a google doc and share with: your partner and blampart@middletowncityschools.com

We will periodically check back and add to the cladogram over the course of the school year.
