<span>The bones in the wings of birds and bats are <u>homologous</u> because they derived from a <u>common</u> ancestor, while the wings are <u>homoplastic</u> traits. Homologous structures are similar structures shared by different groups and that are derived from a common ancestor. The similar anatomy of bones in the wings of birds and bats is inherited from a common ancestor of tetrapods (to which birds and bats belong). However, wings are not inherited from the common ancestor of birds and bats. Therefore, wins are homoplastic traits (analogous structures) because they have similar function but they are not inherited from the common ancentor.</span>
