Detailed explanation-1: -Wings of insects and wings of bats are analogous organs in animals. IV. Thorns of citrus and tendrils of Cucurbita are analogous organs in plants.
Detailed explanation-2: -The wings of birds, hands of humans, and wings of bats are examples of homologous organs.
Detailed explanation-3: -For example, the wings of an insect, bird, and bat would all be analogous structures: they all evolved to allow flight, but they did not evolve at the same time, since insects, birds, and mammals all evolved the ability to fly at different times.
Detailed explanation-4: -Bird and bat wings are analogous-that is, they have separate evolutionary origins, but are superficially similar because they have both experienced natural selection that shaped them to play a key role in flight. Analogies are the result of convergent evolution.
Detailed explanation-5: -Interestingly, though bird and bat wings are analogous as wings, as forelimbs they are homologous. Birds and bats did not inherit wings from a common ancestor with wings, but they did inherit forelimbs from a common ancestor with forelimbs.
