Question

29) Complete the following characteristics on the animal phylogenetic tree. Label each numbered bar with the trait that is characteristic of the lineage. The numbered blanks below give you more room for this exercise. The first one is done for you: multicellularity is characteristic of all animals from Porifera to Chordata. Hint: Some traits will arise more than once on the tree; the number for those traits will appear more than once on the tree. Characteristics: no true tissues, radial symmetry, bilateral symmetry and cephalization, eucoelom, acoelom, diploblasty, triploblasty, protostome development, deuterostome development, segmentation, lophophores, presence of mantle and foot, growth by molting. 1. multicellularity 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14.
