There are ongoing arguments among taxonomists as to which phyla represent the closest relatives of phylum Annelida. Some propose

that these worms share a common ancestor with the arthropods (crabs, insects etc.). However, the majority continue to keep the annelids lumped together with the Lophotrochozoa. The reasons for this are many but probably the least disputed comes from:______.
a. the segmented body plan of the annelids.
b. molecular analysis.
c. metamerism.
d. schizocoelous origin of the coelom.

Answer:

a. the segmented body plan of the annelids

Explanation:

  • lophotrochozoan is a taxonomy of animals that includes annelids, bryozoans, and brachiopods.
  • This taxonomy of creatures was defined in 1995 as the last ancestor of the taxa of worms, mollusks, and annelids. Their classical definition depends on the topology of the spiral tree of life.
  • Annelids have a segmented body part wherein the external morphological features are repeated in every body segment. It allows the animal to become bigger and makes their movement more fat and efficient.
