Among protostomes,which morphological trait has shown the most diversity?

Question

Quizplus · Accepted Answer

Among protostomes, the type of body cavity has shown the most diversity. This is because protostomes have a range of body cavities, including coelom, pseudocoelom, and acoelom. This diversity is largely due to differences in embryonic development and the way in which the body cavity forms. The other traits listed, such as symmetry, number of embryonic tissue types, and direction of gastrulation, are also important in defining protostomes, but they have not shown the same level of diversity as the type of body cavity.
