Origins
Haplogroup P is a branch of Haplogroup MNOPS, which is a branch of Haplogroup K (M9). It is believed to have arisen north of the Hindu Kush, in Siberia, Kazakhstan, Uzbekistan, or along the Silk Road in the region of Xinjiang, Gansu, or Ningxia, before being pressed North, approximately 35,000 years ago. An alternate postulated theory supported by Gansu, Ningxia is that this group moved along the opposite side of the Tibetan plateau along the Sichuan Mountains, before taking the silk route and Bering land bridge. The climate was much different and would have supported more life and grasslands in Tarim Basin, Mongolia, and Manchuria. The sea levels were up to 370 feet lower 18,000 years ago, and significantly lower the last 100,000 years, allowing for an easy expansion of Haplogroup K throughout East Asia, and through the grasslands north of Beijing, going West to the Tarim Basin and North East to Manchuria.
The descendant haplogroups of P include Q (M242) and R (M207).

Famous quotes containing the word origins:
“The settlement of America had its origins in the unsettlement of Europe. America came into existence when the European was already so distant from the ancient ideas and ways of his birthplace that the whole span of the Atlantic did not widen the gulf.”
—Lewis Mumford (1895–1990)
“Lucretius
Sings his great theory of natural origins and of wise conduct; Plato
smiling carves dreams, bright cells
Of incorruptible wax to hive the Greek honey.”
—Robinson Jeffers (1887–1962)
“Grown onto every inch of plate, except
Where the hinges let it move, were living things,
Barnacles, mussels, water weeds—and one
Blue bit of polished glass, glued there by time:
The origins of art.”
—Howard Moss (b. 1922)
