buried at Peschanitsa near Lake Lacha in Arkhangelsk Oblast, Russia c. 10,700 BCE was found to be a carrier of the paternal haplogroup R1a5-YP1301 and the maternal haplogroup U4a. A Mesolithic male from Karelia c. 8,800 BCE to 7950 BCE has been found to be carrying haplogroup R1a. A Mesolithic male buried at Deriivka c. 7000 BCE to 6700 BCE carried the paternal haplogroup R1a and the maternal U5a2a. Another male from Karelia from c. 5,500 to 5,000 BC, who was considered an EHG, carried haplogroup R1a. A male from the Comb Ceramic culture in Kudruküla c. 5,900 BCE to 3,800 BCE has been determined to be a carrier of R1a and the maternal U2e1. According to archaeologist David Anthony, the paternal R1a-Z93 was found at Alexandria, Ukraine c. 4000 BCE, Sredny Stog culture, "the earliest known sample to show the genetic adaptation to lactase persistence (13910-T)." R1a has been found in the Corded Ware culture, in which it is predominant. Examined males of the Bronze Age Fatyanovo culture belong entirely to R1a, specifically subclade R1a-Z93. Haplogroup R1a has later been found in ancient fossils associated with the Urnfield culture; as well as the burial of the remains of the Sintashta, Andronovo, the Pazyryk, Tagar, Tashtyk, and Srubnaya cultures, the inhabitants of ancient Tanais, in the Tarim mummies, and the aristocracy of Xiongnu. The skeletal remains of a father and his two sons, from an archaeological site discovered in 2005 near Eulau (in Saxony-Anhalt, Germany) and dated to about 2600 BCE, tested positive for the Y-SNP marker SRY10831.2. The Ysearch number for the Eulau remains is 2C46S. The ancestral clade was thus present in Europe at least 4600 years ago, in association with one site of the widespread Corded Ware culture. Historical to recent Europe In Europe, the R1a1 sub-clade is found at highest levels among peoples of Central and Eastern European descent, with results ranging from 35% to 65% among Czechs, Hungarians, Poles, Slovaks, western Ukrainians (particularly Rusyns), Belarusians, Moldovans, and Russians. In the Baltics, R1a1a frequencies decrease from Lithuania (45%) to Estonia (around 30%). There is a significant presence in peoples of Scandinavian descent, with highest levels in Norway and Iceland, where between 20 and 30% of men are in R1a1a. Vikings and Normans may have also carried the R1a1a lineage further out, accounting for at least part of the small presence in the British Isles, the Canary
