Textbook Question
Chapter 32, Problem 6TYU
SCIENTIFIC INQUIRY • INTERPRET THE DATA Redraw the bilaterian portion of Figure 32.11 for the nine phyla in the table below. Consider these blastopore fates: protostomy (mouth develops from the blastopore), deuterostomy (anus develops from the blastopore), or neither (the blastopore closes and the mouth develops elsewhere). Depending on the blastopore fate of its members, label each branch that leads to a phylum with P, D, N, or a combination of these letters. What Is the ancestral blastopore fate? How many times has blastopore fate changed over the course of evolution? Explain.
| Blastopore Fate | Phyla |
| Protostomy (P) | |
| Deuterostomy (D) | Echinodermata, Chordata; most Arthropoda; few Mollusca, few Annelida |
| Neither (N) | Acoela |

INSTRUCTIONS:
1. Fill out the blank with their Dichotomous key.2. In each numbered series you should read both choices, determine which choice best applies to the Phylum. Note that some Phyla are already given as guides.3. Proceed where the key tells you to go, often skipping other steps (numbers) in between that do not apply.
