In light of the news about the editing of the human genome, ideas about cosmetic or even functional body transformation no longer seem like fantasy. The other day, Boston College compiled a list of 9 rudiments of the human body, some of which can be removed without harm to the body.

Already 20% of people do not have such muscles, the rest have two or less. They are located in the lower abdomen and do not help in any way with body movements, although they can indirectly affect the appearance.
Human embryos develop as female - only at a certain stage of the process, under the influence of testosterone, they turn into male. However, by that time, the embryo already has time to form nipples, which do not have any functional load in the male body.
A fold of fabric, similar to a membrane in the eyes of amphibians or birds, which with its help cover them from debris. The primates from which man originated, in their mass, have lost it, and if the third eyelid grows, man cannot control and use it for its intended purpose.
