Explanation

All mammals, including mice, whales, elephants, giraffes, and humans, have exactly 7 cervical (neck) vertebrae. This is a remarkable example of evolutionary conservation - regardless of neck length or body size, the number remains constant. The variation comes from the size of individual vertebrae, not their count.
