Textbook Question
Chapter 31, Problem 11PIAT
How did feeding appendages called maxillipeds originate?
Maxillipeds are crustacean appendages that are similar in some ways to walking legs but have a specialized shape that is adapted for handling food. Did maxillipeds evolve from walking legs during the diversification of arthropods?
Which of the following nested groups best describes thetaxonomic context for the question of the origin of maxillipeds?
a. Arthropoda>Ecdysozoa>Protostomia>Crustacea
b. Protostomia>Arthropoda>Ecdysozoa>Crustacea
c. Crustacea>Protostomia>Arthropoda>Ecdysozoa
d. Protostomia>Ecdysozoa>Arthropoda>Crustacea
