Describe in detail about vestigial organs and it's significance.

Dear student,
Please find below the answer:

An organ that was once useful in an animal’s evolutionary past, but now has no apparent nor predictable function. E.g., male mammae, appendix, nictitating membrane. These organs are greatly reduced from the original ancestral form and is no longer functional or are of reduced or altered function.

Vestigial structures provide a clue to the evolutionary history of a species because they are remnants of structures found in the ancestral species.

Hope this clears your doubt.
Regards.
