That different organisms are able to adapt to the same environment.
Common ancestry, of course. All mammals, with few exceptions, have seven neck vertebrae which shows that the common ancestor of mammals very likely had this number of vertebrae.
A close relationship between organisms will be seen in the DNA.
Simply put, common ancestry.

no.
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.
Roots
Homologous = same origin, different function (arms vs. wings) Analogous = same function, different origin (panda thumb)
The Kravic's cycle
Homologous structures have the internal structure, but different functions. For example the human arm, horse foreleg, bird wing, and whale flipper have similar internal skeletal structure, but different external structure because of their different functions. Analogous structures have similar external structure because of similar functions, but dissimilar internal structure. An example of analogous structures would be the wings of an insect and a bird.
They don't. Homologous structures provide evidence for evolution not 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.
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.
