Abstract: By exploring the origin, composition, physical characteristics and evolution of the Uygur nationality we can better reveal historical and cultural changes of this ethnic group, which will benefit the protection and development of this nation. Archaeological anthropology, especially results of molecular archaeology, show that the ancient Xinjiang residents are not from a single ethnic origin but instead include European and Mongolian components. Polymorphisms in physical characteristics and genetic traits of modern Xinjiang residents, especially the difference in Uygurs of different regions is undoubtedly closely related to the ancient complex racial background of this group. Modern Uygur mostly have physical characteristics of Mongolian ethnicity, which shows that the modern Uygur ethnic origin is mainly from Mongolia. Different incidences of Mongolian physical characteristics throughout the Uygur living in different regions of the Xinjiang Uygur Autonomous Region including gradient changes trending from east to west embody indicate how the infiltration and fusion of Mongolian traits developed in the Uygur.
