Artery Evolution

Recently, it has been found that, due to evolution, children are now being born with larger heads, with more babies now being delivered through C-section. Similarly, it has been discovered that humans are now evolving a new artery.

When a child is in the womb there is an artery called the median artery which is continuously transporting blood from the heart to the hands of the child. However after birth, usually this artery is replaced by two other arteries and this one disappears.

Now, by comparing ourselves to humans in the 18th century, there are more people today that still retain their media artery. This could be a way of saying that evolution is still taking place within the human body.

The author of this discovery, Maciej Henneberg, a specialist in anatomy at the University of Adelaide, says that this is an indicator that biological evolution is still ongoing within humans. If we were to quantify this, the researchers found, through cadavers and other means, that in the 1800s only around 10 percent of the total population retained the artery. However, when they studied people from the late 20th century, they found that around 30 percent of the people retained the artery. Through these numbers, researchers have concluded that this is the fastest way the human race has ever evolved in the past 250 years.

They also believe that if the trend were to continue, which generally should considering the principles of evolution, then the median artery which is right now an exception will become a norm and those with no median artery will become an exception. Even though this is a fascinating concept, it could have painful consequences as those with a median artery are more likely to get carpal tunnel syndrome, which can be extremely painful.

The researchers think that change has been genetic due to maternal health issues or possibly due to the mutation of genes within humans. They think that by the year 2100 the median artery should become a norm rather than the exception that it is today.

Whether this would be a positive change or a negative change it cannot be said, however, this does show us proof of how fast human evolution has been taking place and how amazing the concept of evolution truly is.
