Since the wings of insects and birds have different structures (or different designs) but perform similar functions, they are analogous organs. Now, since the analogous organs have different basic design, so they do not indicate a common ancestor for the organism. The analogous organs provide evidence for the evolution in another way.
The presence of analogous organs indicates that even the organisms having organs with different structures can adapt to perform similar functions for their survival under hostile environmental conditions. Thus, the presence of analogous organs in different animals provide evidence for evolution by telling us that though they are not derived from common ancestors, they can still evolve to perform similar functions to survive, flourish and keep on evolving in the prevailing environment. The analogous organs actually provide a mechanism for evolution.

∙ 12y agoWhen referring to the taxonomy of a species, one might encounter a species they have seen before but under further observation, the species observed may have slightly different attributes which are adaptations to its surrounding.
As the world has changed much over the last several hundred thousand years, it is apparent that many species have had to adapt to change in climate by adapting their skin to be more efficient given the stimulus of hot or cold, coats of fur on species that had little, or a shortening of fangs as large game became more sparse in a region. Over many hundreds of years, if a species still remains intact, its adaptation to its environment(s) may well be hypothetically radically changed. Such adaptations over long periods of time may be considered to be evolution.

How does analogous structure support evolution?
Analogous structure supports evolution because some of these structure may have existed long ago, however not all analogous structure support the same evolutionary path.
How do analogous structures and homologous structures differ?
Homologous features of animals are a lot more recent in contrast to evolution, where as analogous dates far back. Homologous features are similar in structure, but perform different functions, such as the human hands and dolphin flippers, which makes room to allow recent evolution comparisons while analogous consists of wings of a bee and a bird, which are completely different. When trying to determine evolutionary relationship between two species, biologists concentrate on homologous features, as analogous features would be considered useless in this case.
How are analogous and homologous structures different?
They are different because homologous structures have the same structure, but serve a different function. Like mammal arms(human, bat and whales). Analogous structues are different structures, but serve the same function. For example, bat wings and butterfly wings.
How Does Homologous Structures Disapprove Evolution?
They don't, Homologous structures, such as the bones in your forearms and the bones in your cat's and dog's forelegs are that similar because you and your pets are mammals and closely related on the evolutionary tree. Before modern genetic showed this to be convincing the study of morphology was showing us pretty much the same thing; homologous structures support evolution.
How does observed evolutionary change support the scientific theory of evolution?
The theory predicts that evolution will happen and in certain ways. The observed evolution makes this prediction correct. It also defines evolution as happening, and as such is perfect evidence in support of it.
What evolution has produced many of the analogous structures in organisms today?
They don't. Homologous structures provide evidence for evolution not analogous structures.
Both homologous and analogous forms of these result from evolution?

How does analogous structure support evolution?
Analogous structure supports evolution because some of these structure may have existed long ago, however not all analogous structure support the same evolutionary path.
What are analogous characteristics?
analogous character similarities that are the same, but found in different species, thought to have arisen from convergent evolution
What are similar structures that evolved independently called?
Similar structures that have evolved independently are called homologous structures. An example would be the wings of a bird and the wings of an insect.
What do the structures that result from convergent evolution indicate about organisms?
The structure that result from convergent evolution indicates that organisms have to be reclassified because when scientists compared nucleic acid from the cells of the animals and they found many diffrences in them.
Is a wing of a bird homologous to the wing of a cat?
In biology, homologous structures are defined as structures which serve the same purposes because they evolved from the same source (divergent evolution), the opposite of analogous structures, which serve the same purpose but evolved through convergent evolution. Birds' wings and bats' wings are both homologous and analogous. As wings, the two are analogous, but as forelimbs, the two are homologous.
How is homologous vs analogous structures a part of evolution?
My spidey senses are telling me to tell you to look in your book.
What evolution is called when unrelated organism live in similar environment?
And come up with similar solutions, both physiological and behavioral? Analogous structures arising from convergent evolution.
What are analogous structures?
Analogous structures are features of two different species that are similar in how the function, but the structure of the two features is different. The wings of an insect and the wings of a bird are analogous structures.
What is analogous evolution?
analogous evolution is when animals have unsimilar structures with similar functions, like the wing of a fly is different from the wing of a bat, but both help the organism to fly regardless. or a seal and penguin both have fish-like bodies, and blubber to keep them warm in arctic conditions, but are related closely...
If Whales and cats are both mammals Are the whale's front flipper and the cat's front leg homologous or analogous and why?
Neither one. Both homologous and analogous structures refer to similar structures. But a cat's front leg and a whale's front flipper have little in common. Homologous structures come from little evolutionary separation, and analogous structures come from convergent evolution. But the differences between a cat's front legs and a whale's front flipper result from divergent evolution. The common ancestor of mammals (cynodonts) has split into various groups with widely differing characteristics. One such group includes cats, and another includes whales. These two groups are not very related to each other, thus having no homologous structures, and have been put in very different environments, thus having no analogous structures.
