    I guess most animal brains increase as body size increases, like Elephant has bigger brain than cat. I wonder if anyone scientifically measured the amount of reactive enzyme or whatever is needed. because maybe we all too much

      @BCsven @GreyEyedGhost There is a lot of work on brain size relative to body weight across species. It’s referred to as an “Evolutionary Quotient”. The relationship between brain volume and body mass is approximately linear overall, particularly in a phylum. There are variations off the linear and we generally associate the positive deviations with “smarter” animals.
