What are the Dolphin origins and were they upgraded to have individual souls?

The dolphins were created, as is true of all species. They were given individual souls from the outset and this is true of all of the whales as well. They were always intended to be important stewards of the ocean and to have dominion of the seas with respect to all levels of life. In that respect, they are what is considered an apex predator in that they can serve to manage fish populations and also the plankton for purposes of keeping things in better balance. This is true of human with respect to land-dwelling creatures. The competition with other predator species was not part of Creator’s plan and has created many difficulties for human. Most famines are owing to the depletion of wildlife across the planet from over-predation.
