New serious mutations found in the human body
Many people no longer grow their wisdom teeth, but an extra artery and bone appear.
Australian scientists said they have discovered a new stage in the evolution of modern humans, in which wisdom teeth disappear and an additional artery appears, according to the Voice of America.
“More and more children in the world are born without wisdom teeth embedded in their jaws,” say Australian scientists after analyzing human development data over the past 250 years. According to them, during the last two centuries, human physiology has changed most rapidly in the history of evolution. modern humans, compared to their relatively recent ancestors, have a smaller face, an extra artery in the forearm, and extra bones in the legs, “says a report by scientists from Flinders University in South Australia.
It is observed that most people are born with wisdom teeth that begin to erupt in adolescence or later. Scientists believe that these teeth were necessary for people in ancient times to chew raw or very solid food, however they are now becoming redundant.
“As the face becomes smaller, there is not much room for the wisdom teeth because the jaw has shrunk,” said Dr. Tegan Lucas of Flinders University.
Scientists emphasize that the appearance of an additional artery in the human forearm is also evidence of rapid evolutionary changes. Before, children were born with this artery and it quickly disappeared, but now one in three people have this blood vessel until the end of their life.
“The study also says that more and more people in the world are born with an extra small bone behind the knee called a fabella. Previously, it was believed that humans lost this bone in the course of evolution,” he said in the message.
Also in the human foot, scientists have noticed additional joints that connect the bones.
Scientists have reviewed the history of human evolution.
Scientists have previously modeled a human in the year 2100. Due to the sedentary lifestyle, the spine will bend in an arc and the elbows will be fixed at a 90% angle.
