   Our results falsify these creationist hypotheses and show that scientists currently identify many structures as vestigial in animals, plants, and single-celled organ-isms. Examples include not only organs but also cells, organelles, and parts of molecules.

   Archetypal examples of vestigial organs include structures such as wings in nonflighted birds, eyes in blind species, and vestigial limbs in snakes. Organs often become vestigial when selection for their original function becomes relaxed. They range from disadvantageous to selectively neutral to slightly advantageous (Gould 1980).

   What is a vestigial structure?

   • Such degenerate structures are called “vestigial of ancestral structures. Biologists recognize vestigial structures as evidence for biological evolution (Starr & Taggart, 2004; Reece et al., 2011). For example, blind cave fishes and sala-manders arguably have eyes only because they inherited them from sighted ancestors.

   Are there vestigial biological structures in biology textbooks?

   • Lists of vestigial biological structures in biology textbooks are so short that some young-Earth creationist authors claim that scientists have lost confidence in the existence of vestigial structures and can no longer identify any verifiable ones. We tested these hypotheses with a method that is easily adapted to biology classes.

   Are vestigial structures inherited?

   • This action is not available. Vestigial structures have no function but may still be inherited to maintain fitness. Structures that have no apparent function and appear to be residual parts from a past ancestor are called vestigial structures.

   Is a structure smaller than an organ a vestigial structure?

   • Structures smaller than organs can also be vestigial. Vestigial organelles have been identified in unicellular organ-isms (e.g., vestigial mitochondria in several species [Regoes et al., 2005] and vestigial chloroplasts in others [Sekiguchi et al., 2002]). Even parts of molecules can be considered vestigial.

   Structures that have no apparent function and appear to be residual parts from a past ancestor are called vestigial structures. Examples of vestigial structures include the human appendix, the pelvic bone of a snake, and the wings of flightless birds.
