1. Appendix.
The appendix is a small pouch located near the junction of the small and large intestines. It was once thought to be a vestigial organ with no function, but recent research suggests it may play a role in the immune system during fetal development. However, in adulthood, the appendix is considered largely useless. It can become inflamed, leading to appendicitis, which often requires surgical removal.
2. Coccyx (Tailbone).
The coccyx is the small triangular bone at the base of the spine. It is a remnant of the tail that our distant ancestors had. In modern humans, the coccyx serves no significant purpose and is often considered a vestigial structure. While it may provide some slight support for sitting, its absence due to injury or surgical removal generally does not impair normal functioning.
3. Darwin’s Point.
Darwin’s point is a small, pointed ear protrusion at the top of the ear’s helix. It’s present in a minority of people and is thought to be a vestigial structure, a remnant of a feature that was once functional in our evolutionary ancestors. Its purpose in modern humans is unclear, and it serves no known function.
4. Palmaris Longus Muscle.
The palmaris longus muscle is a long, slender muscle that runs from the forearm to the palm. It’s absent in about 14% of the population and is considered functionally redundant. While it may have been important for our ancestors in activities like climbing, it has little to no significance in modern human movement. Surgeons often use it for grafts as its removal has minimal impact on hand function…..See More
