Give examples of vestigial structures.
Answer
What are Vestigial Structures?
Vestigial structures are anatomical features or organs in an organism's body that have lost their original function through the course of evolution. These structures may have been functional in ancestral species, but over time, due to changes in the organism's environment or way of life, they have become reduced in size, functionally obsolete, or entirely non-functional.Examples of Vestigial Structures
1. Human Caecum / Appendix / Hair / Coccyx: These are examples of vestigial structures in humans.2. Nictating Membrane in Humans: The presence of a nictitating membrane (third eyelid) is vestigial in humans.
3. Halters in Diptera: Halters are specialized structures found in dipteran insects.
