Üner Tan Syndrome: Review and Emergence of Human Quadrupedalism in Self-Organization, Attractors and Evolutionary Perspectives
نویسندگان
چکیده
The first man reported in the world literature exhibiting habitual quadrupedal locomotion was discovered by a British traveler and writer on the famous Bagdad road near Havsa/Samsun on the middle Black Sea coast of Turkey (Childs, 1917). The man most probably belonged to a Greek family, since the region of Havsa was populated by Greek people during the time of the Ottoman Empire. He possibly belonged to a consanguineous family resident within the closed Greek population, which had a high probability of interfamilial marriages. Childs described this man in his book (p.29) as follows:

Background: Uner Tan syndrome, first described in 2005, consists of three main symptoms: habitual locomotion on all four extremities, impaired intelligence, and dysarthric or no speech. This extremely rare syndrome shows an autosomal recessive inheritance due to consanguineous marriages between parents. In general, there is a cerebellovermial hypoplasia with a mild gyral simplification in the c...

This review includes for the first time a dynamical systems analysis of human quadrupedalism in Uner Tan syndrome, which is characterized by habitual quadrupedalism, impaired intelligence, and rudimentary speech. The first family was discovered in a small village near Iskenderun, and families were later found in Adana and two other small villages near Gaziantep and Canakkale. In all the affecte...

Background. Uner Tan Syndrome (UTS) was first described in 2005 and consists of three main symptoms: habitual locomotion on all four extremities, impaired intelligence with no conscious experience, and dysarthria. Since then, seven further families have been found, mostly in southern and eastern Turkey, giving a total of 23 individuals in eight families exhibiting UTS. We here present three new...

Two consanguineous families with Uner Tan Syndrome (UTS) were analyzed in relation to self-organizing processes in complex systems, and the evolutionary emergence of human bipedalism. The cases had the key symptoms of previously reported cases of UTS, such as quadrupedalism, mental retardation, and dysarthric or no speech, but the new cases also exhibited infantile hypotonia and are designated ...
