  I can’t see how folding a piece of paper changes it’s original volume, it doesn’t loose any molecules in the process, so just how does it change allowing more surface area. Am I looking at this too literally? I can see that it changes the shape, however not the surface volume…that would be a constant right?

    I guess the main point is that it takes much more energy to fold even a slight increase in thickness, making it less likely to happen naturally.

  Folding increases with smaller brains.
  
  Neurons increase with smaller brains, of birds.
