Detailed explanation-1: -Analogous organs evolved when similar evolutionary pressure resulted in the selection of similar adaptive features in different groups of organisms but leading towards the same function. Thus these structures show convergent evolution.

Detailed explanation-2: -Homologous organs perform the same function but are structurally different. The structure of the vertebrae is a common homologous structure in all mammals.

Detailed explanation-3: -Convergent evolution is a kind of evolution wherein organisms evolve structures that have similar (analogous) structures or functions in spite of their evolutionary ancestors being very dissimilar or unrelated.

Detailed explanation-4: -Structures that are the result of convergent evolution are called analogous structures. On the other hand, a homologous structure would have a common origin. Analogous structures refer to unrelated organisms having structures that have the same function but are anatomically different.

Detailed explanation-5: -The process of convergent evolution starts off with two or more unrelated groups getting adapted to a similar environment. By this, they develop more or less similar features, which include analogous organs, i.e., unrelated ancestors “converge” towards the same function while adapting to a similar environment.
