During the course of evolution some organs remain in the organisms.We have studied about appendix in digestive system.In human beings it has no role to play in the process of digestin.But in herbivores like rabbit appendix plays an important role.Such type of organs which are not useful are called vestigial organs.There are nearly 180 vestigial organs in human beings.                                                                 For example:-pinna,hair or skin,mammary gland in human,etc.,Thats why human being is said to be a moving museum of vestigial organs.

The organs which were functional in the ancestors but non-functional and reduced in the descendants are called vestigial organs.
Presence of vestigial organs is the most convincing evidence in favor of organic evolution and also supports the concept of disuse proposed by Lamarack.
In man, there are nearly 180 different types of vestigial organs.
Hence, Weidersheim described human being a "Moving Museum of Antiquities" or a "Moving Museum of vestigial organs".
Eg: Vermiform appendix , coccyx , plica semilunaris , auricular muscles that               move the pinna , hair on the body , mammary glands in males etc.
