NOTES:

Y-DNA haplogroup P, an offshoot of Haplogroup K, originated in Central Asia some 35,000 years ago; sites in Uzbekistan, Kazakhstan and southern Siberia have been offered as the likely point of first appearance. Haplogroup P is best represented by its two immediate subclades, haplogroups Q and R, which expanded to become the dominant haplogroups in, respectively, the Americas and Europe. Undifferentiated Haplogroup P exists in widely scattered locations near the Black Sea (Ossetia), in the Near East (Kurdish Turkey), Central to Eastern Asia (Southern Siberia and Mongolia) and South America (Northeastern Brazil).
