Slavs
Slavs are an Indo-European ethno-linguistic group who speak the various Slavic languages of the larger Balto-Slavic linguistic group. They are native to Eurasia, stretching from Central, Eastern, and Southeastern Europe all the way north and eastwards to Northeast Europe, Northern Asia (Siberia), the Caucasus, and Central Asia (especially Kazakhstan and Turkmenistan) as well as historically in Western Europe (particularly in East Germany) and Western Asia (including Anatolia). From the early 6th century they spread to inhabit the majority of Central, Eastern and Southeastern Europe. Today, there is a large Slavic diaspora throughout North America, particularly in the United States and Canada as a result of immigration.
Kazakhs
According to mitochondrial DNA studies (where sample consisted of only 246 individuals), the main maternal lineages of Kazakhs are: D (17.9%), C (16%), G (16%), A (3.25%), F (2.44%) of Eastern Eurasian origin (58%), and haplogroups H (14.1), T (5.5), J (3.6%), K (2.6%), U5 (3%), and others (12.2%) of western Eurasian origin (41%). An analysis of ancient Kazakhs found that East Asian haplogroups such as A and C did not begin to move into the Kazakh steppe region until around the time of the Xiongnu (1st millennia BCE), which is around the onset of the Sargat Culture as well .
