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. Given that the giraffe's neck is so much longer than ours, some people are surprised we have the same number of neck bones. The fact of the matter is that nearly every mammal has seven neck bones â mice, dogs, and even whales.
However, during normal development several vertebrae fuse together, leaving a total of 24, in most cases. The confusion about whether or not there are 32-34 vertebrae stems from the fact that the two lowest vertebrae, the sacrum and the coccyx, are single bones made up of several smaller bones which have fused together. This is how the vertebrae are counted: 24 separate vertebrae and the sacrum, formed from 5 fused vertebrae and the coccyx, formed from 3-5 fused vertebrae.
