Hello
hhaya0307 , If you want to know about vestigial organs then from some research on internet I found that vestigial organs are those organs which is non functional tissue or organs and for example appendix which is one of the best example.

Hope it will be helpful for you :)

Hello Student,

These 'useless' body-parts, otherwise known as vestigial organs, are remnants of lost functions that our ancestors possessed. They once represented a function that evolved out of a necessity for survival, but over time that function became non-existent. A vestigial structure may retain lesser functions or develop minor new ones.

The examples of human vestigiality are numerous, including the anatomical (such as the human tailbone, wisdom teeth, and inside corner of the eye), the behavioral (goose bumps and palmar grasp reflex), and molecular (pseudogenes). Many human characteristics are also vestigial in other primates and related animals.

Some examples of vestigial organs are:

• Appendix
• Coccyx
• Wisdom Teeth
• Vomeronasal organ
• The outer ear

Hope you find this information useful.

Feel free to ask more questions.

Have a good day!!
