Edward Burnett Tylor's 1871 Primitive Culture, and specifically its second volume on religion, is the founding text of the academic study that first proposed comparing religious belief systematically across the world's peoples, arguing that animism, a belief in spiritual beings, was the earliest stage from which polytheism and eventually monotheism developed. That evolutionary sequence, ranking one people's religion as more developed than another's, has since been abandoned by anthropology as a whole, though the word animism and Tylor's basic comparative method, treating a people's religious life as a subject worth documenting in its own right, both remained in use long after the ranking itself was rejected.
Later ethnography replaced Tylor's evolutionary ladder with sustained fieldwork among a specific people, documenting a group's own beliefs, practices and self understanding in its own terms rather than placing it on a scale toward some other tradition's account of religious maturity, and a culture group entry follows that later standard rather than Tylor's original ranking.
An entry therefore records a people's documented religious life and its own self identification honestly, citing Tylor's own foundational text for the discipline's origin where relevant, while keeping his specific evolutionary claims named as a historical position anthropology has since set aside, not as a live scholarly account of how any people's religion actually developed.
