Question

Quizplus · Accepted Answer

Mollusks and annelids both share a common ancestor within the lophotrochozoan group. This is supported by molecular and morphological evidence such as the presence of a trochophore larva in both groups. Nematodes, vertebrates, insects, and tardigrades all belong to different groups and do not share a common ancestor with annelids within the lophotrochozoans.
