What is special about the mammalian cervical spine?
| June 21, 2021 | education
Mammals have seven cervical vertebrae, the number of which remains constant. This is because mammals are descended from a common ancestor that also had seven vertebrae in the cervical spine, and therefore the almost universal number of seven vertebrae is compelling evidence for evolution.
The only mammals that have developed different numbers of cervical vertebrae for no apparent reason are sloths and manatees. So, two-legged sloths have 5-7 cervical vertebrae, while three-legged sloths have 8 or 9.
