In reference to the origin of life, photosynthesis is more ancient than aerobic cellular respiration because select one: a. plants evolved before vertebratesb. earth's early atmosphere did not have oxygenc. there is no reason for cellular respiration to occur without glucose from plantsd. carbon dioxide was contributing to global warming, to photosynthesizers recycled it.

Photosynthesis operates in plants and initially produced free oxygen to change the atmosphere to support non-plant organisms, consequently, a, plants arose before vertebrates and other oxygen breathing organisms, but plants did not evolve, they were created.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
