Hadar, Ethiopia, as perhaps deliberately moved to the area as a mortuary practice. Later Lower Paleolithic remains have also been interpreted as bearing associations of funerary rites, particularly cannibalism. Though archaeologist Kit W. Wesler states "there is no evidence in the Lower Paleolithic of the kind of cultural elaboration that would imply a rich imagination or the level of intelligence of modern humans", he discusses the findings of Homo heidelbergensis bones at Sima de los Huesos and the evidence stretching from Germany to China for cannibal practices amongst Lower Paleolithic humans. A number of skulls found in archaeological excavations of Lower Paleolithic sites across diverse regions have had significant proportions of the brain cases broken away. Writers such as Hayden speculate that this marks cannibalistic tendencies of religious significance; Hayden, deeming cannibalism "the most parsimonious explanation", compares the behaviour to hunter-gatherer tribes described in written records to whom brain-eating bore spiritual significance. By extension, he reads the skull's damage as evidence of Lower Paleolithic ritual practice. For the opposite position, Wunn finds the cannibalism hypothesis bereft of factual backing; she interprets the patterns of skull damage as a matter of what skeletal parts are more or less preserved over the course of thousands or millions of years. Even within the cannibalism framework, she argues that the practice would be more comparable to brain-eating in chimpanzees than in hunter-gatherers. In the 2010s, the study of Paleolithic cannibalism grew more complex due to new methods of archaeological interpretation, which led to the conclusion much Paleolithic cannibalism was for nutritional rather than ritual reasons. In the Upper Paleolithic, religion is associated with symbolism and sculpture. One Upper Paleolithic remnant that draws cultural attention are the Venus figurines, carved statues of nude women speculated to represent deities, fertility symbols, or ritual fetish objects. Archaeologists have proposed the existence of Lower Paleolithic Venus figurines. The Venus of Berekhat Ram is one such highly speculative figure, a scoria dated 300350 kya with several grooves interpreted as resembling a woman's torso and head. Scanning electron microscopy found the Venus of Berekhat Ram's grooves consistent with those that would be produced by contemporary flint tools. Pettitt argues that though the figurine "can hardly be described as artistically achieved", it and other speculative Venuses of the Lower Paleolithic, such as the Venus of Tan-Tan, demand further scrutiny for their implications for contemporary theology. These figurines were possibly produced by
