These are called homologous structures. Since these structures are so similar, they indicate an evolutionary relationship and a common ancestor of the species that possess them. These types of analogous structures do not prove species are related, but rather they support the Theory of Evolution by show how species do build up adaptations in order to fit into their environments. That is a driving force behind speciation or a change in species over time.
