As the cell adapts to the universal force or stress it gains from the stressful radiation experience. However if there are damaging effects caused by that radiation to certain areas or parts of the cell, the cell has also experienced some loss ,after the loss has been deducted that which remains is called the survival value! So, if the radiation produces 3+ gains and two - losses then the one plus unit of adaptation of success is called a survival value . The survival value is carried throughout the lifetime and enables the organism to adjust to a better expression of the human health. The more units of adaptational success with a higher survival value that a cell has in its lifetime, the better an offspring that cell will beget. If during its lifetime the cell has five positive units it will give that survival value to its offspring“. The new cell will then begin life five units stronger than its parents cell began life this is the chiropractic viewpoint of human change and evolution (not Darwin).
