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 do analogous structures support evolution?
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.
What is analogos?
The Webster's dictionary says: Analogous (biol.) similar in function though differing in structure
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 are some similarities in divergent and convergent evolution?
The adaptive traits that arise through convergent evolution are called analogous. These are the same adaptive solutions that arise in different organisms facing very similar environmental challenges and having analogous mutations to come to similar traits through natural selection. Wings in birds, bats and insects are examples of this.
The evolution of an ancestral species into an array of species that occupy diverse habitats is called?
analogous structure
What evolution has produced many of the analogous structures in organisms today?
They don't. Homologous structures provide evidence for evolution not analogous structures.
How does similarities in body structure support evolution?
it shows how they evolve into another
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.
What are analogous characteristics?
analogous character similarities that are the same, but found in different species, thought to have arisen from convergent evolution
Both homologous and analogous forms of these result from evolution?
Structures
What types of evidence do scientists use to support evolution?
Fossils, D.N.A., vestigial organs or structure, same structure diffrent function.
Which structure of a paramecium is analogous to a reserve copy of all the cell's genes?
Micronucleus is a structure of a paramecium that is analogous to a reserve library
What structure in the human is analogous to the cecum?
appendix
A sentence that uses analogous structure?
6y8
Definition of analogous structures?
An analogous structure is a structure that has a similar function but different components. For example, the wings of a butterfly verses those of a bird. In both cases, the function is flight, but the wings are build differently.
A pattern of evolution that results when two unrelated species begin to appear similar because of environmental conditions is?
Analogous evolution. Convergent evolution.
