This, presumably. With geometric climaxes of energy being different than those of the other sub-atomic particles.
All steps of the branch are similar yet non-identical forms of the predecessor.
Also, for instance (pertaining to the first paragraph) molecules with the same types and amount of atoms interact with their environments in different fashions dependent of how their molecules are arranged. (Left-hand molecules vs. Right-hand molecules) So we could say that the fundamental energy, or the true indivisible form of nature, is simply arranged differently inside of a quark than it's in the other particles.

also quarks form via hadronisation which happens when the QCD field has enough energy to create quarks
