</span>
Vestigial structures have been used for long by evolutionists to support the theory of evolution. These organs are believed to have been in use in the past lives but as the species adapts to new forms of life and lifestyle,the vestige organs becomes obsolete,but are not removed by the body. An example of vestige organs in human being are the appendix,tail bone,and mammalian grands in men.
