The same ancestral bone structure has evolved to produce different forearm functions The mammals do not share a common ancestor. The different bone structures of independent lineages have evolved to produce similar forearm functions The mammals do not share a common ancestor. The similar bone structures of independent lineages have evolved to produce different forearm functions. The mammals share a common ancestor. The forearms of each mammal share a similar ancestral function, despite having evolved differences in bone structure.
