Our closest wormy cousins: About 70% of our genes trace their ancestry back to the acorn worm

For awhile now I have been associating the worm as a pivotal point in evolution, and I have been trying to disassociate the fish from moving onto land. I feel that the fish is not required to move to land when the worm can take that step instead, so the legs that you see on fish really came from the worm moving between land, and sea. The acorn worm is not exactly the worm that would do everything required to merge all species together, you actually need a metamorphic worm which links to the salamander more. The worm would be like a body that changes shape quite readily between fins, and legs, and these changes would be like soft callouses that respond to irritation. So a worm that changes shape to its surroundings like a chameleon that changes colour to its surroundings, but slower than that. I think that the worm could grow soft legs, and bones would come at a later stage, and then lead up to a salamander, and then the salamander leads up to the fish. The fish them mistakenly gets identified with legs as the stage that moved to land, however the legs are from land use already back from a salamander.
