Outline of Final Research Achievements

This study contributes to clarify the evolution of the shoulder girdle, especially of the shoulder girdle muscles, which undergo the big morphological changes from amphibians to mammals. In summary, this study clarifies the following three problems. ①the evolutionary changes of the supracoracoid and the coracobrachialis muscle into the supra/infra spinatus and the biceps brachii muscles following from the reduction of the coracoid bone and newly formation of the scapular spine in mammals, ②the differentiation of the dorsal shoulder muscles, which play an important role connecting the shoulder girdle with the trunk in tetrapods, and the morphological significance of the dorsal shoulder muscles as the trunk muscles by observing precisely the origin of their innervating nerve branches, ③the phylogenetic differentiation of the subscapularis, teres major and latissimus dorsi muscles and the multiple origin of the subscapularis muscle in mammals.
