Uyghurs
Contemporary scholars consider modern Uyghurs to be the descendants of a number of people, including the ancient Uyghurs of Mongolia who arrived at the Tarim Basin after the fall of the Uyghur Khaganate, Iranic Saka tribes, and other Indo-European peoples who inhabited the Tarim Basin before the arrival of the Turkic Uyghurs. DNA analyses indicate that the peoples of central Asia such as the Uyghurs are all mixed Caucasian and East Asian. Uyghur activists identify with the Tarim mummies, remains of an ancient people who inhabited the region, but research into the genetics of ancient Tarim mummies and their links with modern Uyghurs remains problematic, both to Chinese government officials concerned with ethnic separatism, and to Uyghur activists concerned that the research could affect their people's claim of being indigenous to the region.
Afshar people
The Afshar, also spelled Awshar or Afşar, are one of the Oghuz Turkic peoples. These originally nomadic Oghuz tribes moved from Central Asia and initially settled in what is now Iranian Azerbaijan, Azerbaijan Republic, Eastern Turkey. Later some of them were relocated by the Safavids to Khurasan, Kerman and Mazandaran. Today, they are variously grouped as a branch of the Azerbaijanis and Turkmens or Turkomans. 
Afshars in Iran remain a largely nomadic group, with tribes in central Anatolia, northern Iran, and Azerbaijan. They were the source of the Afsharid, Karamanid dynasties, Baku Khanate, Zanjan Khanate and Urmia Khanate.
