Problems and criticisms of the Documentary hypothesis have been brought on by literary analysts who point out the error of judging ancient Eastern writings as if they were the products of western European Protestants; and by advances in anthropology that undermined Wellhausen's assumptions about how cultures develop; and also by various archaeological findings showing the cultural environment of the early Hebrews was more advanced than Wellhausen thought. As a result, few biblical scholars of the twenty-first century hold to Wellhausen's Documentary hypothesis in its classical form. As Nicholson says: "it is in sharp decline—some would say in a state of advanced "rigor mortis"—and new solutions are being argued and urged in its place". Yet no replacement has so far been agreed upon: "the work of Wellhausen, for all that it needs revision and development in detail, remains the securest basis for understanding the Pentateuch".
