Question

we consider wings of bat and wings of bird analogous but what do we consider arms of bat and arms of birds homologous or analogous??

Answer 1

We say the organs are analogous or homologous only when they are comparable with respect to structure or function. The wings of bat and birds are comparable with respect to their function but the arms of bird and bats are neither similar in structure nor function. So, they are not comparable and neither analogous nor homologous organs.
