In the history of Earth and the evolution of cells, aerobic cells appeared first and anaerobic cells appeared later.
Andreas93 [3]

Answer:

False

Explanation:

Scientist believe that the primitive atmosphere lacked free oxygen. Oxygen is a highly reactive molecule that would have made difficult for complex macromolecules to appear and then create life.  Rocks from the precambrian period support this theory.

Anaerobic cells appeared first, then photosynthesis appeared filling the atmosphere with oxygen and the aerobic organism develop cellular respiration to obtain energy, a process more efficient than anaerobic respiration.
