So easy to recognize these five brothers of Turkish origin.They always run a crawl.Not with the knee, but two feet and two hands.Like early humans.
They became the world's attention after the BBC television network broadcast a documentary titled 'The Family That Walks On All Fours', five years ago.The film also shows how they survive in the modern society.
They became the world's attention after the BBC television network broadcast a documentary titled 'The Family That Walks On All Fours', five years ago.The film also shows how they survive in the modern society.
They spent most of his life sitting on the floor outside their home, located in a remote village.However, one brother they had traveled out of the village and involved interaction with modern humans.
When the documentary aired, five siblings, aged 18 to 34 years.Those who are descendants of Kurdish tribes in the interior of Turkey, looks so free to move with two palms and the soles of his feet.While her face looked up facing forward.
They could not stand upright on two legs.When pressed, they will stand with the knees bent and head up.Two female and one male of five siblings were completely unable to walk on two legs.While the other two are still able to walk on two legs though staggered.
Though oddly, the existence of this family contribute to research on human evolution from walking to crawling to walking upright.Scientists believe that the conditions they can give different and more detailed explanation of the earlier theories, related to human evolution.
The results showed, the presence of genetic abnormalities that make them run a crawl.This can provide valuable information about how humans evolved and ancient human with four legs evolved into humans with two legs.
"It is really amazing as an example that shows the development of human disorders. But, their purpose of life is how to survive in the modern world," said Professor Nicholas Humphrey, evolutionary psychologist at the London School of Economics, was quoted as saying by the Daily Mail.
Professor who has visited the family twice to say that the five siblings have mental retardation.Their parents are believed to provide a unique combination of genes that lead to that limitation.
Some researchers argue, the genetic fault has triggered the development of early humans they like or 'backward evolution'.While other researchers believe it is caused by brain damage that allows processes running does not work.
They prefer to walk with their palms compared to running on the joints of their bodies like gorillas or chimpanzees.The researchers believe this may be the way early humans walked protect their fingers with a more subtle movement.
Professor Nicholas Humphrey said that what the family is returning to instinctive behaviors that are encoded deep in the brain, and was ignored during evolution.
"I do not think they are destined to become four-legged animals, but they have unique genes that make them like this," he said.
