ABSTRACT
Chapter 8 mainly focused on actinopterygian and sarcopterygian fi shes. The present chapter focuses mainly on the Sarcopterygii as a whole (including extant actinistians, dipnoans and tetrapods) and particularly on the way in which the pectoral and pectoral fi n/forelimb muscles have evolved during the transitions from sarcopterygian fi sh and non-mammalian tetrapods to monotreme and therian mammals and to modern humans (Fig. 9.1).
