Although we are willing to believe that we are the ultimate goal of natural evolution, humans are far from perfect. We’re obviously a lot different from primate ancestors, but our evolutionary journey is still taking place, and new research reveals an adaptation that is increasingly happening in newborns and could be the next major change in humans.
The study, published in the Journal of Anatomy, reveals that “more” arteries are becoming more common in the human arm. The researchers believe this may be an evolutionary change, suggesting that our species is still changing slowly.
As ScienceAlert reports, researchers have found that when babies develop in the womb, an artery is usually active, but over time it disappears, but now more and more newborns keep it. This change is a small change, but it is still important because scientists hope to hone the evolutionary changes the human body is still undergoing.
“Anatomists have been studying the prevalence of this artery in adults since the 18th century, and our study shows that it is clearly increasing,” study lead author Dr. Teghan Lucas said in a statement. “The probability of this artery occurring in people born in the mid-1880s is about 10 per cent, compared with 30 per cent for people born at the end of the 20th century, so this is a significant increase in evolution in a relatively short period of time.”
The researchers call the change “micro-evolution” and say that if the trend continues, most people will have more arteries in their arms by the end of the century.
“This increase may be due to a genetic mutation in the development of participating arteries or the mother’s health problems during pregnancy, or both. If this trend continues, arteries in the forearms of most people will become the norm by 2100. “
While this may seem obvious, it is actually just one of several changes that humans have experienced over a considerable period of time. The researchers compared the increasing rate of discovery of the positive arteries with the trend towards the disappearance of newborn wisdom teeth. Over time, the likelihood of a person being born without wisdom teeth is increasing, which makes sense, because in modern humans, wisdom teeth tend to cause more problems than they solve.
So while humans may not have developed the ability to telepathy or bend spoons with their minds, at least we know that evolution is still making us better myself.
