Likewise, much of The Urantia Book material relating to the evolution of mankind appears to have been directly taken from Henry Fairfield Osborn, Man Rises to Parnassus: Critical Epochs in the Prehistory of Man published by Princeton University Press in 1928.
Samuti paljud Urantia raamatu inimkonna evolutsiooni kajastavad materjalid tunduvad olevat võetud otseselt Henry Fairfieldi teosest "Man Rises to Parnassus: Critical Epochs in the Prehistory of Man" (Inimese tõus parnassile: eelajaloolise inimese kriitilised epohhid), mille andis 1928. aastal välja kirjastus Princeton University Press.
