Explain the terms analogous and homologous organs with examples.

(N/A) Homologous organs are those that have a similar basic structural design and developmental origin,but perform different functions. For example,the forelimbs of humans and the wings of birds have a similar skeletal structure,indicating a common evolutionary origin,but they perform different functions (grasping vs. flying).
Analogous organs are those that have different developmental origins and structural designs,but perform similar functions. For example,the wings of a bird and the wings of a bat are analogous. While both are used for flight,the wing of a bird is supported by the entire arm,whereas the wing of a bat is a fold of skin stretched between elongated fingers. This indicates that they evolved independently to serve the same function.
