RNA demethylation increases rice and potato yields 50%
I am going to ask a noob question: if this change is beneficial to plants, why has it not occurred already by natural mutation?Evolution can be blind "hill-climbing", so if it's a step towards "local maximum", why has it not already been taken? Is it not a "local" step (i.e. hard to occur naturally) or not "towards maximum"  (i.e. good for the farmer but not for the plant)
