Comparative anatomy is the study of similarities and differences in the anatomy of different species.It is closely related to evolutionary biology and phylogeny (the evolution of species).. It is important to distinguish the shoulder/scapulohumeral joint from the entirely muscular connection (synsarcosis) between the forelimb and the trunk.
