Answer:
The vertebrae formed about 500 million years ago. The Cambrian eruption began when sea creatures formed vertebrates that caused them to walk upright. They do not have a backbone yet, however, only "notocards", which are made of a substance similar to cartilage.

The spinal cord in vertebrate animals transforms in the following way;
- The spinal cord is the information pathway that connects the brain to the peripheral nervous system.
- It begins from the brainstem.
- Early development of the spinal cord begins within the mother's womb.
- A mother's diet, nutrition intake plays a major role in the closure of the neural tube.
- It is from this neural tube the spinal cord emerges and develops.
- Its remaining development relies on the neural crest.
- By the age of four, the spinal cord develops completely.
