The commonality is the presence of Hox genes.                                                  Hox genes are a group of genes that control basic body plan formation. They are responsible for the location of body parts and this explains why many organisms or animals share similar body types. For example these genes help lay out the basic body forms in many animals, including humans, flies, and worms. Additionally, they set up the head-to-tail organization.
