“…Only a few studies have attempted to relate cervical form to neck function across primates (Ankel, ; Gómez‐Olivencia et al, ; Gommery, ; Schultz, , ; Toerien, ), and even fewer have tested functional hypotheses in a comparative biomechanical framework (Manfreda et al, ; Meyer et al, ; Nalley, ; Nalley & Grider‐Potter, , ; Parks, ). Some of these studies have had some success in understanding the influences of locomotion on vertebral morphology (Manfreda et al, ; Meyer et al, ; Nalley, ), but the use of categorical estimates of locomotor behavior has imposed limitations to connecting form and function. For example, in their geometric morphometric analysis of C1 morphology, Manfreda et al () did not find a relationship between locomotor categories and concavity of the superior articular facets.…”
