Humans are undergoing a “microvolution”, resulting in babies being born without wisdom teeth and with extra arteries in their hands, Australian Australian researchers say.
Scientists believe that humans are evolving rapidly at any stage in the last 250 years – more children emerge with shorter faces, smaller jaws and extra bones in the legs and feet.
Surprising findings were part of a study in the journal Anf anatomy.
The extra artery is the middle artery that forms for the first time in the uterus and serves as the main vessel that delivers blood to the front and arms, according to Sky News. Once the radial and alveolar arteries develop, however, the arterial artery is destroyed, although now one in three people keep it for life.
There is no health risk with the outside body part, which increases the blood supply to the hands.
“This is a ‘micro-evolution’ in modern humans,” said Professor Kiez Heinberg, professor of the study. Have. “
The BBC’s Science Focus report says that if the trend of microevolution continues, people born years from now will have a middle artery.
Wisdom teeth can also be a thing of the past. Smaller faces mean less space for teeth – although the ability to chew food can be increased due to the lack of wisdom teeth.
Tegan Lucas, a doctor at Flinders University in Adelaide, Australia, told Science Focus, “This is happening on time because we have learned to use more fire and food. Many people are just born without wisdom teeth.”
To get their findings, the researchers looked at the rate of recovery of certain body parts and analyzed the corpses of people born in the 20th century.
They found that some people were born with extra bones in their arms and legs or even with abnormal connections of two or more bones in their legs.
“Many people believed that humans evolved. But our study shows that we are still evolving – faster at any stage in the last 250 years.
