How do animals obtain nutrients? - Using directed movement to find food. Then ingest prey and digest it with their bodies. What are the traits that make animals unique (i.e., that are not seen in other organisms)? - Muscle and Nervous Cells What organism is the evolutionary ancestor of animals, and what evidence do we have for this relationship? - Choanoflagellates. They are identical to "collar cells" in sponges, which is the basal group of animals. What phylum is the basal (earliest evolv...

I have color coded and organized the groups of animals into protostomes, deuterostomes, and the phylum within along with important characteristics. There is also information on thermoregulation within the animals and maintaining homeostasis.
