1. RHYTHMS IN HUMAN NATURE



     12

     I tentatively conclude from this that our vulnerability to perturbation, because it is itself subject to natural selection, has evolved to give us tools for restoring or replacing rhythms under varying assaults from inside and outside. Since rhythmic organization is the foundation for many life processes (and for the human meaning bestowing experiences we have already touched on) a selective process to restore rhythm to disturbed body processes, probably through epigenetic signals to clock genes, would have increased our fitness. This could explain why rhythm and phase resetting capabilities are found everywhere in nature.

     We are creatures built of multiplexed, nonlinear bio-oscillating systems partly coupled to the surrounding medium, partly resistant to it and partly rhythmically dominating it. This is to say that when we are perturbed we are adapted to respond to it. We try to resist disruption. We make efforts to restore rhythmic functioning. We will fight off or get away from the perturbing forces. Our physiology is designed to return to homeostasis. A robust response to perturbation allows for adjustment, repair and renewal. The plasticity in the nervous system, the duplications of pathways, the alternate routes in the brain, the cascading interactions of biochemical processes on regulatory genes all cope with perturbation.
