What is the difference between analogous and homologous organs?
Characteristics of different species are said to be analogous when having the same biological function, for example, the wings of bats and the wings of insects. Characteristics of different species are said to be homologous when having the same biological origin, i.e., when they are products of differentiation of a same characteristic from a common ancestor, like cat paws and human feet. (Characteristics of different species may be analogous and homologous.)
