There are many assumptions about the function and formation of the chin. For years, it has been the subject of heated debate in the field of evolutionary anthropology. Many scientists believe that it has no function and that it is a bizarre result of human genetic and evolutionary development.
Another widespread idea is that a pronounced chin is a symbol of good genes and testosterone. Small chins are associated with weakness, and large - with strength and masculinity.
Other very popular hypotheses suggest that the chin is needed to aid speech, others believe that it balances chewing or that it is simply a lateral formation that has arisen from the transition from four to two legs.
We mentioned above that the chin is a symbol of good genes, but there is no evidence that men choose their partner on this part of the face. It turns out that the attractiveness of this part of the face goes unnoticed and unappreciated.
Researchers at the University of Florida in the United States have conducted new research showing that changes occurred six million years ago that led to the appearance of a chin. Scientists have found that during this period man began to cook and gradually stopped consuming solid foods.
Man gradually began to eat softer foods. This change made large teeth and strong jaws superfluous. The size and strength of the teeth and jaws decreased over the next two million years, and so the chin appeared.
Dr. Pampush and his team conducted a study on more than 100 species of primates, collecting data on their chins and comparing them with historical data. With the help of computer modeling, they tracked the rate of change in the lower part of the chin.
Dr. Pampush believes that cooking has led to the formation of a chin in Homo erectus, or in other words in the Upright Man. According to the scientist, the erect person has spent less time eating, the teeth have become smaller and this may be the reason for the formation of the chin as an arch.
