heterogeneity

The children of the Fulcrum are all different: different ages, different colors, different shapes. Some speak Sanze-mat with different accents, having originated from different parts of the world. One girl has sharp teeth because it is her race's custom to file them; another boy has no penis, though he stuffs a sock into his underwear after every shower; another girl has rarely had regular meals and wolfs down every one like she's still starving. (The instructors keep finding food hidden in and around her bed. They make her eat it, all of it, in front of them, even if it makes her sick.) One cannot reasonably expect sameness out of so much difference, and it makes no sense for Damaya to be judged by the behavior of children who share nothing save the curse of orogeny with her.

Evolution is an integration of matter and concomitant dissipation of motion during which the matter passes from an indefinite incoherent homogeneity to a definite coherent heterogeneity, and during which the retained motion undergoes a parallel transformation.
