Most Mammals Have 7 Cervical Vertebrae â Not Quite Enough to be Evidence for Evolution Giraffes have seven cervical vertebrae (neck bones), the same number as humans.

Chapter 39: The vertebral column. Vertebral column in general. The vertebral column usually consists of 33 vertebrae: 24 presacral vertebrae (7 cervical, 12 thoracic, and 5 lumbar) followed by the sacrum (5 fused sacral vertebrae) and the coccyx (4 frequently fused coccygeal vertebrae). The 24 presacral vertebrae allow movement and hence render the vertebral column flexible. Stability is provided by ligaments, muscles, and the form of the bones. The abbreviations C., T., L., S., and Co. are used for the regions, and these are sometimes followed by V. for vertebra or N. for nerve.
