Evidence for biocultural evolution during the Upper Pleistocene may exist in the form of craniofacial morphological differences between premodern humans and modern humans because, as one interpretation mentioned in your text suggests… Group of answer choices deep concentration on the creation of cave art murals resulted in the selection for more gracile craniofacial morphology in modern humans hunter gatherers used landscape surveying methods to hunt and gather resources, a practice that required long periods of squinting resulting in supraorbital browridge muscle robusticity frequent spiritual rituals focused around chanting practices resulted in enlarged craniofacial muscle attachments basket weaving techniques required the use of the teeth as a clamp to temporarily hold the sinew technological innovations assisting with food processing resulted in anatomically modern humans not needing large teeth and facial muscles to chew and process their foods
