Middle Paleolithic humans' use of burials at sites such as Krapina, Croatia ( BP) and Qafzeh, Israel ( BP) have led some anthropologists and archaeologists, such as Philip Lieberman, to believe that Middle Paleolithic humans may have possessed a belief in an afterlife and a "concern for the dead that transcends daily life". Cut marks on Neanderthal bones from various sites, such as Combe-Grenal and Abri Moula in France, suggest that the Neanderthals—like some contemporary human cultures—may have practiced ritual defleshing for (presumably) religious reasons. According to recent archaeological findings from "Homo heidelbergensis" sites in Atapuerca, humans may have begun burying their dead much earlier, during the late Lower Paleolithic; but this theory is widely questioned in the scientific community.
