area, i. e., Uralic and Yeniseian. Physical appearance The Andronovo have been described by archaeologists as having cranial features similar to ancient and modern European populations. Andronovo skulls are similar to those of the Srubnaya culture and Sintashta culture, exhibiting features such as dolicocephaly. Through Iranian and Indo-Aryan migrations, this physical type expanded southwards and mixed with aboriginal peoples, contributing to the formation of modern populations of India. Genetics Fox et al. (2004) established that, during the Bronze and Iron Age period, the majority of the population of Kazakhstan (part of the Andronovo culture during Bronze Age) was of West Eurasian origin (with mtDNA haplogroups such as U, H, HV, T, I and W), and that prior to the thirteenth to seventh century BC, all Kazakh samples belonged to European lineages. Keyser et al. (2009) published a study of the ancient Siberian cultures, the Andronovo culture, the Karasuk culture, the Tagar culture and the Tashtyk culture. Ten individuals of the Andronovo horizon in southern Siberia from 1400 BC to 1000 BC were surveyed. Extractions of mtDNA from nine individuals were determined to represent two samples of haplogroup U4 and single samples of Z1, T1, U2e, T4, H, K2b and U5a1. Extractions of Y-DNA from one individual was determined to belong to Y-DNA haplogroup C (but not C3), while the other two extractions were determined to belong to haplogroup R1a1a, which is thought to mark the eastward migration of the early Indo-Europeans. Of the individuals surveyed, only two (or 22%) were determined to be of Asian ancestry, while seven (or 78%) were determined to be of European ancestry, with the majority being light-skinned with predominantly light eyes and light hair. In a June 2015 study published in Nature, one male and three female individuals of Andronovo culture were surveyed. Extraction of Y-DNA from the male was determined to belong to R1a1a1b. Extractions of mtDNA were determined to represent two samples of U4 and two samples of U2e. The people of the Andronovo culture were found to be closely genetically related to the preceding Sintashta culture, which was in turn closely genetically related to the Corded Ware culture, suggesting that the Sintashta culture represented an eastward expansion of Corded Ware peoples. The Corded Ware peoples were in turn found to be closely genetically related to the Beaker culture, the Unetice culture and particularly the peoples of the Nordic Bronze Age. Numerous cultural
