It seems clear that the metazoan ancestor inherited from its unicellular descendants an actin cytoskeleton and motor-proteins of the myosin superfamily. Within metazoans, these two molecules were arranged into effective contractile units, the muscles. The basic trends for muscle evolution are already expressed in the diploblastic taxa.[well established][VHOG]
