first of all l want to suggest that this is not ferm statement . This had been said by scientist . that a animal in water was birth 1 st . and then becoz of changing
environmental factors , they were converted from unicellular to multicellular organisms. And 1 st organism was respire by anaerobic respiration . They were underdeveloped
animals. But , after some years , they were converted to devoloped organism
and they stated to respire by aerobic
respiration. then scientist of this generation has classify them based on
with oxygen and without oxygen. With oxygen it is called as aerobic and without it is called as anaerobic respiration.
