“Not only is the mitochondria DNA inherited solely from the mother, but this DNA suffers progressive damage throughout women’s lives. The damage results in further mutations in the mitchondrial DNA. These mutations are cumulative and therefore, increase in number with each successive generation. In other work, each new generation escaping the rigors of the survival of the fittest will suffer more health problems than the last.” -Dr. Mark Starr
