C4 plants evolved when CO₂ partial pressure was low and there was a higher partial pressure of oxygen in the air, which is the opposite of the trajectory we see

C4 plants evolved when CO₂ partial pressure was low and there was a higher partial pressure of oxygen in the air, which is the opposite of the trajectory we see today. Therefore, we have reduced the selection pressure on C4 plants. Rather than try to go against this evolutionary process, we have incorporated natural processes from other plants and algae to achieve the same effect of avoiding photorespiration.
