Question

Why are the wings of butterflies and birds called analogous organs?

Options

• They look alike and serve the same function, but are not anatomically similar structures.

• They have a common origin but perform different functions.

• They have the same basic arrangement of humerus, radius, and ulna.

Answer 1

The wings of butterflies and birds look alike and serve the same function. However, they are not anatomically similar structures, so they are analogous organs.
