scoundrel [369]

Answer:

Because the have similar limbs.

Because they have similar functions.

Explanation:

(because they have similar limbs)

Homology (evolution) describes a structure that has similar function like limbs on dogs and bears (used for walking) and also have a similar arrangement of bones. The fins on a doplhin might be different from the wings on a bat but they reflect a common origin due to their bone composition e.g carpals and radius bones.

(because they have similar functions)

Analogy (evolution) describes a structure with  for example, bird and butterfly wings that have no common ancestor but have the same purpose, in this case flying. They developed independtly as adaptions. This supports natural selection which is a driving force for evolution.
