Each group of organisms shown in the cladogram uses a different mechanism to cope with the production of nitrogenous waste. The point marked X best represents which evolutionary development? Mamm Amphibians Bony fahes Cariaginous fshes The scarcity of fresh water resulted in the evolution of a uric acid metabolic pathway. The toxicity of ammonia led to a tolerance for greater concentrations of urea in the bloodstream. The move to terrestrial environments favored the use of ATP to produce a two- nitrogen compound from ammonia. The rapid metabolism associated with the development of limbs required the excretion of greater amounts of urea.
