Turkish siblings moving all fours, baffle scientists Walking all fours might be fun for some, but for the of one Turkish family, it’ the only way move around, according the BBC. Five siblings of the 19-member Ulas family, Hatay Province, suffer a rare disability – they lack the balance and stability required stand up straight, forcing them move all four limbs.

The family, were first discovered 2005, featured a BBC documentary film the following year. The film revealed that of the five siblings, two sisters and a brother have only walked all fours since birth. Another brother and sister sometimes manage walk upright. “It’ amazing as an example of a strange, strange aberration of human development,” said Professor Nicholas Humphrey, visited the family twice during the documentary. “But interest is how they can live the modern world.”

As a result of the disorder, the siblings are often ridiculed. However, the family has found a way round ordeal by letting the sisters remain indoors most of the , spending crocheting. One of the brothers, on the other hand, is more adventurous – he travels to the local village and interacts other people.

According to the film, a popular explanation for their unusual walk – similar to the movement of primates – was ‘reverse evolution’. Many scientists believed that the siblings were living proof that it is possible for humans to devolve. “ do not think they were destined to be quadrupeds by their genes, but their unique genetic make-up allowed them to be.” said Professor Humphrey.

So scientists believe that the gait could be a byproduct of a hereditary condition that causes cerebellar hypoplasia, which disturbs their sense of balance. The siblings may have developed quadrupedalism order to adapt to the rare condition known as Uner Tan syndrome, named after the Turkish evolutionary biologist first studied them.

Well, it seems that while scientists are busy finding theories to explain the rare condition, there is no real cure in sight. The Ulas siblings probably have to walk this way for the rest of their lives.
