Dyssocials: a dangerous by-product of evolution?
16 Autoimmunity
In this process of developing control systems, there is also the case of developing factors (enzymes), which trigger the destruction of units (cells) which are very functional and useful. In this case we can speak of autoimmunity: units are destructed which are very functional and whose destruction can endanger the survival of the whole entity.
