Chapter 32, Problem 8TYU
SYNTHESIZE YOUR KNOWLEDGE
This organism is an animal. What tan you infer about its body structure and lifestyle (that might not be obvious from its appearance)? This animal has a protostome developmental pattern and a trochophore larva. Identify the major clades that this animal belongs to. Explain your selcction, and describe when these clades originated and how they are related to one another.

Jointed appendages
Cephalization
Tissues
