Members of the Turkish family Ulas can only move on all fours

Scientists knocked tolku



Walking on all fours can seem to someone funny, but for the members of a Turkish family is the only way to travel. Five brothers and sisters of the 19 members of the Ulas family from the province of Hatay are suffering from a rare type of disability - they lack balance and stability required for bipedal locomotion, which is why they can only move on four legs.

The BBC in 2006, he made a documentary film about the brothers and sisters Ulas' Family walking on all fours. " Of the five people, only two sisters and one brother, walked on all fours with the birth. More one brother and sister sometimes possible to walk only on the legs. "This is a wonderful example of a very strange violations of human development," - said Professor Nicholas Humphrey, who visited the family twice during filming.





Over brothers and sisters often laugh because of their illness, and the family trying to do everything possible to protect them. The sisters most of the time at home knitting, one of the brothers more adventurous - he goes to a nearby village and interact with other people.





According to the film, a popular explanation for their unusual gait - similar to the movement of primates - a "reverse evolution". Many scientists believe that this family - living proof that people can devolyutsionirovat. However, there is move the limbs in a different order than primates.

Now scientists believe that the strange gait can be side effect of inherited diseases caused by cerebellar hypoplasia, which violates the sense of balance. The brothers and sisters of this step could develop in order to adapt to a rare disease known as syndrome Yunera Tan, accompanied by severe mental retardation.



While scientists are developing theories to explain a rare disease, there is no effective treatment. Perhaps the brothers and sisters will have to spend as Ulas rest of his life.
