The Genes that control development in different vertebrates are only slightly different from each other
All vertebrates exhibit similar forms during development due to their shared evolutionary ancestry and common genetic regulatory mechanisms. The similarity arises from conserved developmental pathways and genes, such as Hox genes, which guide the formation of body structures. These developmental processes reflect fundamental biological principles that govern the growth and organization of vertebrate organisms, despite the diversity seen in adult forms. As a result, early embryonic stages appear remarkably similar across various vertebrate species.
Fish, they had the first vertebrate
Yes, it is a vertabrate.It has a backbone.Part of the back bone is what forms the tail.
Embryonically, they represent inverted forms of each other.
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.

Ontogeny recapitulates phylogeny, or the development of the individual summarizes the evolution of the species. For example, human embryos go through a stage in which they develop gills as did their aquatic forerunners.
Scientists infer that vertebrate species share a common ancestor due to similarities in early developmental stages, such as the presence of pharyngeal slits, a notochord, and a dorsal nerve cord in embryos. These shared embryonic features suggest a common evolutionary origin, as they are observed across various vertebrate species despite differences in adult forms. Additionally, the patterns of organ development and skeletal structure further support the idea of a shared lineage among vertebrates. Such developmental similarities align with the principles of evolutionary biology, indicating descent from a common ancestor.
