Men’s breast button
The debate about whether or not men should wear breast buttons is never-ending. Breast buds are formed two months after the baby is born in the womb, but due to the influence of the Y chromosome, the development of the baby’s breasts stops. As a result, even in adulthood, the breasts continue to grow a little and remain “useless organs”.
Early human ancestors may have needed a tail for balance. One of the proofs that humans had tails is that there are still rare cases of people being born with tails. But modern man finds his balance so well that there is no need for tails. In the mother’s womb, the human “tail” is formed for 5-8 weeks and stops.
Over time, due to the influence of food, the human jaw has become smaller, and there is no room in the mouth for the molars. However, some people are still “suffering” from growing molars. As molars are often a major problem and are of little importance to mastication, their role is one of the most pressing issues for dentists.
The appendix, or appendix, is a worm-shaped growth of the appendix and is a useless “organ” in the digestive process located almost at the border of the small intestine.
If you look closely, you can see red skin inside the eyes and on the nose. The third eyelid of birds and lizards is a useful organ for protecting and moisturizing the eyes, but it is useless “skin” for humans.
