- What are the evolutionary advantages of possessing vertebrae?Describe the last vertebra of the DOG. How is it different from the other cervical vertebrae?How do the “types of vertebrae” change throughout the evolution of vertebrate taxa, from fish (2 types) to amphibians(4 types)? Relate those changes to the functional demands on the skeleton—changes related to the move from water to land, need for support, locomotion.
