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.
Structures found in various species that may have the same function, but have originated from somewhere different on the evolutionary chain. See convergent evolution.
Homologous Structures
They don't. Homologous structures provide evidence for evolution not analogous structures.
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.
analogous character similarities that are the same, but found in different species, thought to have arisen from convergent evolution
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.
Homologous Structures
Analogous structures fit your definition.
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.
They don't. Homologous structures provide evidence for evolution not analogous structures.
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.
Yes, homologous structures have common bone and muscle structures suggesting that they came from an common ancestor while analogous structures do not share any similarity in features, suggesting that they derived from two separate origins.
Similar structures that evolved independently are called analogous structures, or analogies.
no
Roots
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.
Structures
Homologous = same origin, different function (arms vs. wings) Analogous = same function, different origin (panda thumb)
