Vestigial organs An idea destructive to medical science and our health Editor’s note: Since this 1998 article was written, research has uncovered more functions for such things as the appendix. Vestigial structures are actually the “footprints” of embryology and the “footprints” of the efficiently engineered designs of our common Designer, God. The term vestigial implies a lack of use, purpose, or function. A "vestigial structure" or "vestigial organ" is an anatomical feature or behavior that no longer seems to have a purpose in the current form of an organism of the given species.Often, these vestigial structures were organs that performed some important functions in the organism at one point in … Vestiges are remnants of evolutionary history—“footprints” or “tracks,” as translated from the Latin vestigial.

Vestigial structures are often called vestigial organs, although many of them are not actually organs. All species possess vestigial features, which range in type from anatomical to physiological to behavioral. Some structures due to less or no utility, degenerate over a period of time to avoid consequences of genetic drift or selective pressures. Vestigial organs vary from being pointless to favourable based on the selection. For decades, the appendix was thought of as a completely vestigial organ, serving no purpose at all. Another so-called vestigial organ finds a function. Listed among Wiedersheim’s “vestigial” organs were such organs as the parathyroid, pineal and pituitary glands, as well as the thymus, tonsils, adenoids, appendix, third molars, and valves in veins.1 All of these organs have been subsequently shown to have useful functions and indeed some have functions essential for life.
