After badyzing more than 20,000 studies conducted in 27 countries over 150 years, the researchers said that a bone, which they thought was lost in human evolution, had reappeared in recent years.
The evolution has left many vestiges in the human body and these have become insignificant in the daily functioning of modernity. A group of researchers discovered a bone apparently without function and thought itself lost in the chain of evolution but it has reappeared forcefully in recent years.
The researchers badyzed more than 20,000 studies in 27 countries over a 150-year period, estimating that the appearance of this bone had tripled between 1918 and 2018. It is called "Fabela" and it's a small bone that is embedded in a tendon behind the knee.

The Imperial school of london was the one who initiated this study conducted by Michael Berthaume, who said: "We do not know what is the function of the fabela in the human, no one has ever explored it".
This survey found that according to the data of the year 1895, 17.9% of the population had this little bone, but according to the 1918 figures, this percentage fell to 11.2%. It is estimated that the percentage would continue to decrease until it disappears completely but, as confirmed, its current presence has occurred more frequently.

Berthaume He also badured that at the moment, they are managing two options for which there are Fabela: "It can act like other sesamoid bones to help reduce friction in the tendons., redirecting the muscle forces or, as in the case of the patella, increasing the mechanical strength of this muscle. Or I could not do anything at all. "
