In other words, they did not evolve independently (...) (5) The divergence of vertebrate skeletal and cardiac muscles/vertebrate smooth muscle and nonmuscle is at least before that of vertebrates/arthropods. In other words, emergence of skeletal and cardiac musle type tissues preceded the vertebrate/arthropod divergence (ca. 700 MYA).[well established][VHOG] TODO - add skeletal muscle organ?
