Later defenders of the out of Asia theory included Henry Fairfield Osborn, Davidson Black, and William King Gregory. Henry Fairfield Osborn was best known for his Dawn Man theory of human origins which he wrote would be found in Tibet and Mongolia. Osborn firmly believed that Asia had been the cradle of humankind.[14] Davidson Black writing a paper in 1925 titled Asia and the dispersal of primates wrote that the origins of man were to be found in Tibet, British India, the Yung-Ling, and the Tarim Basin of China.
