Haplogroup R0

[6] R0 has likewise been observed among mummies excavated at the Abusir el-Meleq archaeological site in Middle Egypt, which date from the Pre-Ptolemaic/late New Kingdom, Ptolemaic, and Roman periods.

[7] The 3rd century AD Catholic Church Saint, Fortunato of Serracapriola, was also found to carry the R0a'b subclade.

[citation needed] R0 today occurs commonly in the Arabian peninsula, with its highest frequency observed nearby among the Soqotri (40.7%).

[10] Additionally, moderate frequencies of R0 occur in Northeast Africa, Anatolia, the Iranian Plateau and Dalmatia.

The haplogroup has been observed among Chad Arabs (19%),[11] Sudanese Copts (13.8%),[12] Tigrais (13.6%),[8] Somalis (13.3%),[8] Oromos (13.3%),[8] Afar (12.5%),[8] Amhara (11.5%),[8] Gurage (10%),[8] Reguibate Sahrawi (9.26%; 0.93% R0a and 8.33% R0a1a),[13] Gaalien (9%),[12] Beja (8.3%),[12] Nubians (8%),[8] Arakien (5.9%),[12] Yemenis (5.1–27.7%),[8] Iraqis (4.8%),[8] Druze (4.3%),[8] Palestinians (4%),[8] Algerians (1.67%),[13] and Saudis (0–25%).
