What is analogous to the wing of a bird?
The wings of a butterfly and the wings of a bird are analogous, but not homologous. Some structures are both analogous and homologous: the wings of a bird and the wings of a bat are both homologous and analogous.
Why the wings of butterfly and birds are called analogous organs?
Analogous organs have similar functions but different structures, origins. Wings of the butterfly are made of chitin and wings of a bird is made up of feather and some bones. Their function is to fly but their anatomical structure is different. So, they are called analogous organs.
Why do bats and birds both have wings?
They are homologous because many anatomical features arise from the same foundational elements. It is the same forelimb in both organisms, incorporating the same foundational bones, the same foundational muscles, blood vessels, nerves, etc.
Why is the insect wing analogous to the bird wing and not homologous?
Insects have two pairs of wings, while bats and birds each have one pair. Insect wings lack bones, but bird and bat wings have them. Butterfly wings are covered in scales, bird wings in feathers, and bat wings with bare skin. All of these organisms have adapted to life in the air and in doing so have evolved wings.
Why are wings analogous?
For example, the wings of a fly, a moth, and a bird are analogous because they developed independently as adaptations to a common function—flying. The presence of the analogous structure, in this case the wing, does not reflect evolutionary closeness among the organisms that possess it.
What are analogous organs What is convergent evolution?
Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups. Bird, bat, and pterosaur wings are analogous structures, but their forelimbs are homologous, sharing an ancestral state despite serving different functions.
Which one of the following is an example of analogous organs?
Wings of birds and butterfly.
How can you tell that insect wings and bird wings are analogous structures?
Bird wings and insect wings are analogous structures. Both of these species have wings that they use for flight and yet their wings came from dissimilar ancestral origins.
Are bird and bat wings analogous?
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.
What are the examples of analogous organs?
Example of analogous organ is the wings of the insect and the wings of the bird. The structure of wings of the bird has bones covered by flesh, skin, and feathers. Whereas the wings of insect is an extension of integument.
Are wings homologous or analogous?
A butterfly or bird’s wings are analogous but not homologous. Some structures are both analogous and homologous: bird and bat wings are both homologous and analogous.
Why are birds an example of convergent evolution?
Birds and bats have homologous limbs because they are both ultimately derived from terrestrial tetrapods, but their flight mechanisms are only analogous, so their wings are examples of functional convergence. The two groups have powered flight, evolved independently. Their wings differ substantially in construction.
