The apical portion of a bird and bat wing is homologous, true or false? This really confuses me I think the answer is true because all of the bone structures come from a common ancestor but how do I know if something is analogous. Or am I wrong when I stay its true?

The basic bone structure did come from a common ancestor and is homologous, but the development of those bones into a wing happened convergently in bats and birds: note that their common ancestors did not have wings. Wikipedia calls this parallel evolution of flight "analogous", but my prof preferred to used "analogous" to describe similarities like those between a human leg and an insect leg, which couldn't possibly be homologous.

I'm not sure if this term is used in English, but in German, a situation like this (convergent evolution of homologous structures) is referred to as a Homoiologie.

I guess it depends on what the question is referring to: individual bones are homologous, but the arrangement of those bones into a wing is not.
