More people are being born without their wisdom teeth in recent years, said a new study that was published recently.
In what we are considering as observable evolving in humans, a study that was published in the Journal of Anatomy suggests that humans are evolving faster than it has done at any other point in the last 250 years.
A team of scientists from Australia found that modern babies are being born with shorter faces, smaller jaws, and no wisdom teeth.
Dr. Teghan Lucas, who is from Flinders University in Adelaide, said that their increased ability to eat and chew food has helped humans evolve.
This has resulted in fewer people being born with wisdom teeth.
This is happening in time as we have learnt to use fire and process foods more. A lot of people are just being born without wisdom teeth.
The research, which was carried out by Lucas and University of Adelaide professors Maciej Henneberg and Jaliya Kumaratilake, also showed that some people are being born with additional bones.
These bones are in their arms and legs.
Abnormal connections of 2 or more bones in their feet are being observed.
In addition to the study that was carried out, the study also found a significant increase in the prevalence of the median artery since the late 19th century.
The artery is the main vessel that supplies blood to the forearm and hand. It forms while the baby is growing in the womb. However, during gestation, it disappears and is replaced by the radial and ulnar arteries, which are the 2 main arteries of our body.
Authors of the study added:
But increasing numbers of cases retain it, so a person can have all three arteries. This evolutionary trend will continue in those born 80 years from today, with the median artery becoming common in the human forearm.
The authors of the study suggest that this is the microevolution in modern humans that is being observed by us.
This is ‘micro evolution’ in modern humans. The median artery is a perfect example of how we are still evolving because people born more recently have a higher prevalence of this artery when compared to humans from previous generations.
Lucas, the other author of the study, said that a lot of people believe that humans have stopped evolving, but that is not true.
Studies that have been carried out shows that humans are still evolving, at a point that this is the fastest evolution in the last 250 years.
