1. The size of the brain relative to the whole body increases in certain evolutionary lines.
2. Increased specialization of function.
3. The increasing sophistication and complexity of the forebrain.
The neural tube develops into the vertebrate spinal cord. It forms early in embryonic development from a flat sheet of neural ectoderm that rolls into a tube, eventually differentiating into the brain and spinal cord.
cerebrum, cerebellum, and the brain stem
Perhaps the most significant evolutionary trend among the metazoan invertebrate phyla is that of cephalization. This term refers to the development of a head, containing a brain. Another process called segmentation allowed animals to develop distinct body parts, such as legs, wings and feelers.
A vertebrate's backbone protects the spinal cord, which is a bundle of nerves that carries messages between the brain and the rest of the body. The backbone also provides structural support and flexibility for the body.
The three visible parts of the brain while looking at a non-dissected Ventral view are the Cerebral Cortex, the Pons and the Medulla.
Embryonically, they represent inverted forms of each other.
One trend in human evolution is the increase in brain size over time, reflecting a gradual development in cognitive abilities. Another trend is the bipedalism, or the ability to walk upright on two legs, which distinguishes humans from other primates.

Yes. Dogs are vertebrates, and one of the defining features of a vertebrate is a cranial neural enlargement often referred to as the brain.
Vertebrate; rhinocerous have a vertebral column (backbone).
