The 20th century brought to the fore the supremacy of genetics, the time in which the secret of life was about to be explained by the DNA held within the double helix of our chromosomes. With our mapping of the human genome, at the last century’s close, after only a short time of examination and study, the secrets of life would begin to be revealed and, with them, the keys to defeat disease and, through our manipulations of these genes, our ability to design improvements that would make us resistant, or even immune, to many of our maladies. Available to us as well would be the ability to select desirable qualities in our progeny. It might even make possible the knowledge and technologies to stop, or even reverse, aging. Genes held the key within their previously unknowable ‘blueprint’ guiding the development of each individual, of every species. Industries have sprung up around this. Billions, even trillions of dollars, stand to be made as we approached our coming futures. But, as is so often the case with science, advances in knowledge bring with it entirely new questions, and what once promised to be explicable, becomes shrouded in an unexpected haze of complexity.
