Question
MAKE CONNECTIONS Historically, annelids and arthropods were viewed as closely related because both have
body segmentation. Yet DNA sequence data indicate
that annelids belong to one clade (Lophotrochozoa) and
arthropods to another (Ecdysozoa). Could traditional
and molecular hypotheses be tested by studying
the Hox genes that control body segmentation (see
Concept 21.6)? Explain.
