Which observation is inconsistent with haeckel's idea that "ontogeny recapitulates phylogeny"? group of answer choices the backbone all tetrapod embryos display pharyngeal clefts, a notochord, segmentation, and paddlelike limb buds. the pharyngeal clefts and branchial arches of embryonic mammals and reptiles never acquire the form seen in adult fish. in reptile embryos, two bones develop into the articular bones of the hinge of the jaw, while these same bones become the hammer and anvil of the inner ear in marsupials. snakes and legless lizards develop "leg buds" as embryos, only to have them reabsorbed prior to hatching.
