You know what parts of the body we don't need anymore? During the phase of evolution, which is counted in millions of years, our body went through radical changes. While adapting to the challenges of time, some things developed, some "disappeared", and then there are parts of the body and abilities that remained, but today they only make a "crowd" and a "show". Meet the seven body parts that once played an important role for the human species, but evolution put them on the bench, where they still warm the bench instead of being "sold". Male nipple? Why do men need her??? Wisdom tooth or appendix?
