physiology. This was especially true for our central nervous system, as we adapted in uniquttways to the
demands of our physical environment. It is safe to say that at some point in thc remote past our evolving
nervous system produced a brain of considerable complexity. Not just any brain, but a thinking brain that was
supremely capable of permitting a wide range of new behaviors. When this occurred, early humans were no
