The Mystery Of The Family Running The Crawl

So easy to recognize the five brothers from Turkey. They always run crawl. Not with the knees, but rather two soles of the feet and two Palms. Like the ancient human.
Them to the attention of the world after the BBC television network aired a documentary entitled ' 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 with sitting on the floor of their House, located in a remote village. However, one brother they had traveled out of the village and involved interaction with modern humans.
The documentary was aired, five siblings were aged 18 to 34 years. Those are the descendants of the Kurds, the outback in Turkey, looks so he could freely move with two Palms and the soles of his feet. While his face looked up facing forward.

They could not stand upright on two feet. When forced, they will stand by the position of the knee bend and head looked up. Two women and one man from the five brothers were completely unable to walk with two legs. While the two others are still able to walk with two legs despite staggered.
Even though it looks weird, the existence of the family contributed to the research on the evolution of human beings from walking to crawl up to run with upright. Scientists believe that the conditions they can give different explanations and more detail than previous theories, related human evolution.
The results showed, the existence of genetic abnormalities that make them run crawl. This can provide valuable information on how humans evolved and ancient man with four legs evolved into humans with two legs.
"This is amazing for example disorder that shows human development. But, their goal of life is how to survive in the modern world, "said Professor Nicholas Humphrey, evolutionary psychologist at the London School of Economics, as quoted from the Daily Mail.

Professor who has visited the family twice said that five brothers have mental retardation. Their parents are believed to provide a unique combination of genes that lead to limitations.
Some researchers argue, the genetic fault had triggered the development of their ancient human tub or ' backwardness of evolution '. While other researchers believe that as a result of brain damage that allow the process running does not work.
They prefer to walk with their palms than running by using the segment-a segment of their body such as gorillas or chimpanzees. The researchers believe, this may be the way the ancient human running protect their fingers with a smoother movement.
Professor Nicholas Humphrey said that the family was returning to the instinctive behavior is encoded in the brain, and unnoticed during evolution.
"I don't think they are destined to become a four-legged animals, but they have unique genes that make them like this," he said.
