Experimental evidence shows that the process of glycolysis is present and virtually identical in organisms from all three domains, Archaea, Bacteria, and Eukarya. Which of the following hypotheses could be best supported by this evidence?

Not all organisms have mitochondria. Similarly, not all organisms use anaerobic respiration. Most mammals, including humans, use aerobic respiration.

It is unlikely glycolysis arose due to convergent evolution, which implies that the different domains all had different ways of obtaining energy and gravitated towards glycolysis, a rather inefficient process.
