Which one of the following describes correctly the homologous structures?
Which one of the following describes correctly the homologous structures?
organs with anatomical similarities, but performing different functions
organs with anatomical dissimilarities, but performing same function
organs that have no function now, but had an important function in ancestors
organs appearing only in embryonic stage and disappearing later in the adult
Solution
The organs which have the same structure and origin but look different and perform different functions are called homologous organs. The organs which have the same function and are superficially alike but are quite different in their fundamental structure and embryonic origin are called analogous organs.
