An analogy is a trait or an organ that appears similar in two unrelated organisms
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.

My spidey senses are telling me to tell you to look in your book.
They are analogous. The function is different, but they have a common ancestoral origin.
Evolution causes certain things to appear in different animals when used for the same function. These are called 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.
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.

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)
