The Most Recent Molecular Evidence Suggests That the Annelida and Mollusca

Essay

The most recent molecular evidence suggests that the Annelida and Mollusca are more closely related to each other (in the clade Lophotrochozoa)rather than either phylum is to the Arthropoda (clade Ecdysozoa).Do you think 1)it matters that this distinction is made,and 2)should the use of molecular evidence by itself be the sole means of distinguishing the affinities of these groups? Support your argument.
