Brain Science: The Theory of Neuronal Group Selection (TNGS) is proposed, based on three principles: during early fetal brain development (Developmental Selection), patterns of neuronal connections are formed through epigenetic variations (i.e., not just hardware variations but those that depend on which neurons are activated); then (Experimental Selection), the environment exerts its influence on variations in synaptic length; finally (Reentry), a very high number of reciprocal and redundant (degenerate) connections are established both locally and over long distances.
