The 11 pages that link to Vestigiality, each with the reason it gives.

• Comparative anatomyRelated: Reduced anatomy can preserve evidence of an organism's evolutionary history.

• HomologyRelated: Vestigial structures reveal homology despite major changes in form or function.

• Common descentRelated: Vestigial structures make sense as modified remnants of ancestral traits.

• Evolution of cetaceansRelated: Reduced pelvic bones and hind-limb remnants preserve evidence of terrestrial ancestry.

• FlightlessnessRelated: Small wings in flightless birds can retain traces of ancestral flight anatomy.

• TailRelated: A short or hidden tail can persist after its original function has diminished.

• HindlimbRelated: Some vertebrates retain reduced hindlimb structures after losing their locomotor role.

• DorudonRelated: Dorudon's tiny hind limbs persisted despite no longer supporting terrestrial walking.

• Goose bumpsRelated: Human goose bumps retain a response more useful when ancestral bodies had thicker fur.
