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.
Analogous structure supports evolution because some of these structure may have existed long ago, however not all analogous structure support the same evolutionary path.
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.
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.
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.
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.
Structures
Analogous structure supports evolution because some of these structure may have existed long ago, however not all analogous structure support the same evolutionary path.
Convergent evolution is the process by which unrelated organisms evolve similar traits or structures in response to similar selection pressures in their environment. This results in analogous structures that serve similar functions despite not being derived from a common ancestor. Examples include the wings of bats and birds for flight, or the streamlined bodies of sharks and dolphins for efficient swimming.
The evolutionary process that produces analogous structures is called convergent evolution. Convergent evolution refers to the independent evolution of similar traits in species that are not closely related, usually in response to similar environmental pressures.
Homologous structures are similar in structure but can serve different functions in different species due to evolution from a common ancestor. Analogous structures, on the other hand, have a similar function but arise independently in different species due to convergent evolution.
Similar structures that evolved independently are called convergent evolution. This occurs when different species adapt to similar environmental pressures and develop analogous traits, even though they do not share a common ancestor that had those traits.
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.
My spidey senses are telling me to tell you to look in your book.
Analogous characteristics are traits or features that are similar in function or purpose but have different evolutionary origins. For example, the wings of birds and insects are analogous structures because they both serve the function of flight, but have evolved independently in each group.
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.
Convergent evolution is when unrelated organisms develop similar traits or characteristics due to living in similar environments. This can result in analogous structures that serve the same function but have different evolutionary origins.
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.
