Uner Tan is/was a Turkish Neurosurgeon born on May 1, 1937. He is most famous for the discovery, documentation, and study of a neurological condition known as Uner Tan Syndrome, a proposed syndrome that has been cited as an example of "backwards evolution." Uner Tan Syndrome is primarily neurological in nature, with its most visible symptom is the natural preference for quadrupedal movement, or in layman's terms, motion utilizing all four limbs instead of just the legs, against what is generally expected in humans. Other symptoms include a lack of fine motor coordination in the limbs, involuntary eye movement, and overall underdevelopment of the cerebellum (the region of the brain responsible for motor control.) There is room for variations, as the syndrome is responsible for symptoms unique to an individual. Other symptoms include limited speech and cognitive functions, both also neurological in origin, though their relationship with the main symptom of quadrupedal movement is uncertain.
