What are vestigial organs?

Answer 1

A vestigial trait (i.e. organ, appendage, etc) is a remnant part of an organism that historically was very important but evolutionarily is no longer needed. For example, the tailbone on humans is considered vestigial because it serves little to no purpose, although at one point it most likely connected to a tail.

Another example is the dew claw on a dog (the small, dangling claw on a dog's front paws). Clearly there's no use for it today, but at one point it may have served an important purpose for survival.

appendix

wisdom teeth

tailbone

male nipples xD

Answer 2

Tailbone is the best example others have possible uses like the tonsils in your throat.

• Appendix
• Male breast tissue and nipples
• Wisdom teeth
• Coccyx (tailbone)
• Erector pili

Answer 3

Vestigial organs are body parts that have lost their original function through evolutionary changes, but are still present in the body. Examples include the appendix in humans and the pelvis in whales. These organs are remnants of our ancestors' evolutionary history.

Answer 4

Darwin argued that useless limbs and leftover organs are evidence of evolution

Answer 5

A vestigial organ is an organ that has no beneficial use to an organism. Ex. Tail bone in Humans

Answer 6
