This is not to invalidate beneficial mutations by any means, what is merely trying to be emphasized is the essence of mutational change is degradation of the genome as time goes on. Recently as of April of 2007, such findings have been clearly observed in many instances. The ''Proceedings of the National Academy of Sciences'' (PNAS) had published within it an online paper. The definate conclusion implied is that when beneficial mutations begin to accumulate, natural selection takes hold and accelerates the mutation rate. Since benefits to fitness are being produced they begin to establish themselves in a population, eventually however there is, "increased deleterious load. | This is not to invalidate beneficial mutations by any means, what is merely trying to be emphasized is the essence of mutational change is degradation of the genome as time goes on.
