What are homologous organs ? Give one example. Can the wings of a butterfly and the wings of a bat be regarded as homologous ? Give reason in support of your answer.
Homologous organs are those organs which have the same basic structure design and development but different functions and apperance.
Eg - Forelimbs of reptiles, amphibians, birds and mammals.
The wings of a butterfly and the wings of a bat cannot be considered homologus because both the wings perform same function but their structure and apperance are not similar.
