![]() Thus, these structures are example of Vestigial structures. In the above given example, pelvis and femur are the vestigial structures. ![]() Get FREE solutions to all questions from chapter EVOLUTION. A vestigial structure is described as a biological structure that has lost a major ancestral function and is usually significantly reduced in size. Adaptations, therefore, need not be adaptive, as long as they were at some point. Watch complete video answer for Which of the following is examples of vestigial structure of Biology Class 12th. ![]() Vestigial traits can still be considered adaptations because an adaptation is often defined as a trait that has been favored by natural selection. Homologous structures indicate common ancestry with those organisms that have a functional version of the structure. Evolution gives answers to how we advance as humans by evidence provided from fossils and DNA. This leads to the discovery of a logical reason known as evolution. Humans are curious creatures and finding out where they come from is one way to satisfy their curiosity. The vestigial versions of a structure can be compared to the original version of the structure in other species in order to determine the homology of the structure.
