Does a giraffe or human have more back bones?

A giraffe has more back bones than a human. Both species have seven cervical vertebrae in their necks, but a giraffe has a total of 18 vertebrae in its spine, while a human has 24 vertebrae. The additional thoracic and lumbar vertebrae in giraffes contribute to their long necks and overall height. Therefore, giraffes have more back bones overall.
