Supernumerary lumbar rib in human prehistory
Unlike their cervical counterparts, supernumerary lumbar ribs are generally considered to be of little clinical significance, though they do constitute a topic of anthropological interest. The two most complete Neandertal lumbar regions (Kebara 2 and Shanidar 3) both show evidence of articular facet...

Unlike their cervical counterparts, supernumerary lumbar ribs are generally considered to be of little clinical significance, though they do constitute a topic of anthropological interest. The two most complete Neandertal lumbar regions (Kebara 2 and Shanidar 3) both show evidence of articular facets for bilateral lumbar ribs and a high incidence of the condition has been reported in the prehistoric Sadlermiut Eskimo. This pilot study tests the association of bi‐iliac breadth with the presence of supernumerary lumbar rib in two wide‐bodied prehistoric populations: Pt.
