Detailed explanation-1: -However, the wings of bats and insects have evolved from very different original structures. This phenomenon is called convergent evolution, where similar traits evolve independently in species that do not share a recent common ancestry.

Detailed explanation-2: -The wings of a bird and of an insect are analogous organs. Both of these species have wings that they use for flight and yet their wings came from dissimilar ancestral origins. The popular theory as to the evolutionary origin of birds is the therapod dinosaurs, specifically, members of Maniraptora.

Detailed explanation-3: -The correct answer is (a) these organisms are unrelated but have similar adaptations. Convergent evolution occurs when two unrelated species face similar evolutionary pressures, causing them to develop similar adaptations.

Detailed explanation-4: -Convergent evolution is the process whereby organisms not closely related, independently evolve similar traits as a result of having to adapt to similar environments or ecological niches. The wings of a bird and the wings of an insect are analogous structures and represent convergent evolution.
