What evolves to become the ancestor of all four limbed animals?
All four-limbed animals belong to the clade of Tetrapoda. The clade of Tetrapoda is defined as the first basal four-limbed animals and all their descendants, extant and extinct. The clade immediately superior (ancestral) to that is the clade of Teleostomi, which contains all jawed vertebrates, including the tetrapods, bony fish, and the extinct lineage of acanthodian fish.
