The embryonic structure that is replaced by the vertebral column in vertebrates is the notochord. The notochord is a flexible rod-like structure that forms in the early stages of embryonic development and provides support for the developing nervous system. In vertebrates, including humans, the notochord is eventually replaced by the vertebral column, which provides greater support and protection for the nervous system.
