Strange Syndrome: All 5 brothers and sisters go by four limbs like bears

A family of 5 siblings in Turkey drew scientists' debate about a strange syndrome. All are not going with 2 legs but with both hands and 2 legs.

The Ulas family was first discovered in 2005. They are Kurds, living in a remote area in southeastern Turkey. Recently, the debate about their strange syndrome rises again after the BBC made a documentary about 5 brothers, according to Tribun News.

Scientists have come up with many different theories about this strange syndrome . Some hypotheses doubt that these 5 siblings have a brain defect that makes it difficult for them to stand upright. Some even argue that genetic problems may cause them to return to the form of four limbs of human ancestors.

Grandparents Resit and Hatice have 19 children. 12 people develop normally, while the remaining 7 suffer from a syndrome that causes them to go with all limbs. Their palms touch the ground, while their legs are straight, their gaits are like those of bears. One in seven people died, five went with four limbs, the other one could walk straight but the staggered gait was drunk.

Among 5 people with this condition, 4 are female including Safiye, Hacer, Senem and Emine. The other member is Mr. Hüseyin, according to IBT Times.

The strange syndrome that appeared in these 5 siblings showed the characteristics of our primate ancestors before they evolved and knew how to go straight, the evolutionary biologist Uner Tan, of the University of Great Medicine Study Çukurova (Turkey), said.

Professor Stefan Mundlos, a German geneticist, thinks that these five siblings may lack a gene that governs the ability to walk straight on two legs.

Another theory comes from British evolutionary psychologist Nicholas Humphrey. He suspected 5 siblings were injured in the cerebellum . The cerebellum is responsible for balancing and orienting. Therefore, damaged cerebellum will lead to disorders in gait and balance, according to IBT Times.
