Which bacteria is more advanced in terms of evolution? Obligate or facultative.

Answer 1

I would believe facultative bacteria since it isn’t dependent on oxygen requirements to reproduce. It can switch to either respiration or fermentation. It can adapt to its environment whereas, obligative requires specific conditions and cannot adapt. I hope this helps.
