Key Features of Vestigial Structures
Some of the key features of Vestigial Organs are:
- These organs have either very insignificant or no function as compared to their ancestral counterparts.
- Vestigial organs usually fail to evolve as they are not found to be necessary with changing environmental conditions that lead to evolution.
- Their presence acts as remnants of their ancestral form which gives a huge amount of information about how the evolution took place.
- They provide significant insights into how the organism might have evolved in response to possible environmental changes.
- These vestigial organs may be found in multiple species which is proof of shared ancestry and evolutionary relationship.
- Comparative anatomy of such vestigial organs helps scientists to determine an evolutionary tree or phylogenetic tree.
- The Vestigial Organs of one species may be a functional organ of another species based on the evolutionary pathway both organisms took.
Vestigial Organs – Definition, Features, Importance, List of Vestigial Organs
Vestigial Organs are one of the most prominent pieces of evidence of the evolutionary process. They are the remnants of the evolutionary past. The presence of vestigial organs shows that evolution may result in loss of function of certain organs. Vestigial organs are proof of the redundancy of certain anatomical structures in the process of adaptation of an organism to changing environmental conditions.
Vestigial organs in humans are the appendix and coccyx which in due course of time and the evolution of human anatomy have become non-functional yet present in the body. Other vestigial organs examples are sinuses, eye membranes, tonsils, etc.
