How do you imagine human beings in 100 years? You probably thought of anatomical evolutions like skin, height and increased cognitive abilities. But what if you were told that at this very moment, with each person born, there are subtle variations that already count as “evolution”? Read and see more about extra artery, this anatomical variation that already exists in humans.

Artery that should disappear after growth is still present in some people
According to researchers from Flinders University and the University of Adelaide, in Australia, an artery that occupies the center of the arm human while it is in the uterine phase, it is not disappearing as often as before. Resulting in adults having an “extra artery”, basically an anatomical variation.
According to Thegan Lucas, an anatomist at De Flinders University, anatomists have been studying the prevalence of this artery since the eighteenth century, and this new study carried out by both universities, proved that the incidence of these cases really only increases.
“The prevalence was about 10% in people born in the mid-1880s, compared with 30% in those born in the late 1880s. 20th century, so that's a significant increase in a fairly short period of time when it comes to evolution." Completed Lucas.
Understand more about this artery.
This extra artery is called the “median artery” and appears right when we are in the uterine phase, that is, it assists in our development, transporting blood from our arms to our hands, which are in the development phase. growth. However, it is common that around 8 weeks, the medial artery undergoes regression and there is space for the radial vessel and the ulnar artery to assume this role.
Today, the median artery is three times more common in humans than it used to be. Thus, it could be concluded that it is natural selection that favors organisms that cling to this “extra” supply in order to survive.
