    Paleobiological Perspectives on the Early Upper Paleolithic Human Transition in the Northwestern Old World by Erik Trinkaus

    Published 2001-11-01
    “…Despite a series of paleobiological similarities involving cognitive, masticatory and locomotor behaviors, as well as temporal and cultural overlap between the two groups, there remain contrasts in the anterior dentition, the upper limb, femoral structural patterns, stress levels, demographic profiles and stable isotopes. These changes reflect principally the improvements in technology and subsistence of the earlier Upper Paleolithic. …”
