A SUMMARY, WITH MANY SUGGESTIONS FOR THE FUTURE
Geneticist George Church wrote in the Prologue to this 2012 book, “biological organisms [can] be viewed as a kind of high technology, as nature’s own versatile engines of creation … with appropriate changes to their genetic programming, they could be made to produce practically any imaginable artifact… Synthetic biology and synthetic genomics, the large-scale remaking of a genome, were attempts to capitalize on the facts that biological organisms are programmable manufacturing systems., and that.. small changes in their genetic software … can effect big changes in their output.” (Pg. 4) He continues, “at least at the microbial level, nature has been redesigned and recoded in significant ways. Genomic engineering will become more common, less expensive, and more ambitious and radical in the future as we become more adept at reprogramming living organisms, as the cost of the lab machinery drops… the question was not so much what they can be made to do but what they can’t be made to do.” (Pg. 7)
He notes, “An additional benefit of engineering a sweeping multivirus resistance into the body is that it would alleviate a common fear concerning synthetic biology---the accidental creation of an artificial supervirus to which humans would have no natural immunity.” (Pg. 9)
He states, “the answer to the question… Can a synthetic chemical copy itself and evolve without help from living systems?---is a resounding yes… shape and function can be altered radically with just a few changes that nevertheless yield a selective advantage at each separate age.” (Pg. 32)
He acknowledges, “Attempts to build a synthetic cell have not been entirely successful… A truly synthetic cell is one that we create ourselves, , from the ground up. This could be a new form of living matter fabricated out of pure ingredients. Such a cell might tell us something about the original cells that arose at the dawn of life on earth… Nevertheless, successfully creating a synthetic cell would represent a key advance in the understanding of living processes. For life, like a machine, cannot be understood simply by studying it and its parts, life, to be understood, must also be put together from its parts.” (Pg. 51-52)
He suggests, “Genome engineering will allow us to become ever more diverse, enhancing our prospects for survival. We are already extending the bodily properties of our species in several different ways. For example, we are making attempts to improve our health, lengthen our life span, and boost our immune system and disease resistance, among other things. We can also adapt to a very high and very low population densities as occurs in space exploration… One of the primary errors of eugenics was the search for an optimal genetic specimen…. One of the main lessons that we learn from nature is that species that are lowest in diversity are most vulnerable to extinction. Consequently I am proposing a vision of maximal genomic diversity.” (Pg. 59)
He observes, “The list of genes that scientists have discovered grows by the day: there are genes for cystic fibrosis, skin cancer, lung cancer, and on and on. Other genes control height, weight, and a host of other traits… Undoubtedly, some people will object to modifying the human genome in this way on a variety of grounds: moral, philosophical, political, religious, aesthetic---and let’s not forget just plain emotional grounds… Objections to new technologies … typically peak as the technology is poised to spread among early adopters but doesn’t yet work well. Then, once the technical bug are ironed out, the high moral ground can invert… with respect to human longevity, how many of us really want the status quo prolonged?” (Pg. 85)
He says, “Cancer-seeking stealth bacteria and humanized mammals for monoclonal antibody production show that genomic engineering can improve human health. Still, these two technologies are mopping-up operations, interventions employed only after a disease occurs. A better application of synthetic genomics would be to prevent diseases from every occurring by altering the human genome, directly reengineering ourselves to higher levels of health, hardiness, and disease resistance.” (Pg. 119)
He explains, “The most obvious reason for resurrecting extinct species is to attenuate, even partially, the wave of mass extinction that is currently taking place… If the continuing loss of countless species is a tragedy, then the introduction of effective countermeasures, and the increase in species diversity that will accompany them, can only be viewed as a benefit.” (Pg. 140)
He points out, “increasingly, some of the world’s most imaginative, significant, and potentially even the most powerful biological structures and devices were now coming not from biotech forms or from giant pharmaceutical companies, but from the ranks of university, college, and even secondary school students, who were doing it mainly in the spirit of advanced educational recreation. Proof of the power and allure of redesigning life.” (Pg. 201)
He notes, “More than three thousand human diseases are known to be caused by a specific gene or a combination of them… we can now pinpoint, with literally atomic accuracy, the molecular basis of many human pathologies. For many such cases, we are reaching a major goal, in the reduction of health and disease states to their ultimate physical foundations in the human genome… Thus the importance of the Human Genome Project as well as that of its latter-day descendent, the Personal Genome Project.” (Pg. 204-205)
He continues, “The original goal of the Personal Genome Project (PGP) was to sequence the genomes of 100,000 volunteers at no cost to them, and to publish the results on the Internet along with the individual’s personal data, even down to their picture. Of course, any such plan immediately raises privacy issues… The solution was to accept into the program only people who… consider that the benefits to society outweigh the risks…” (Pg. 211)
He asks, “Is cloning a possible route to immortality? Overy twenty species of animals have been cloned… Some of the clonings are routine procedures with a clear agricultural benefit. Cloning is sometimes viewed as dangerous, but many new technologies go through a phase in which they are actually unsafe, and the technology is banned at least locally. This is often followed by a phase in which the public demands the technology… A similar progression may be occurring with regard to cloning… One of the most common objections people make about the prospect of human immortality is the unintended consequences of overpopulation. They also worry about long-lived individuals taking away jobs from younger people…” (Pg. 221)
He explains, “The term ‘transhuman’ … [means] above or beyond… The transhuman occupies an intermediate state between a normal biological human and one of the posthuman variety, a being whose capabilities so far outstrip those of ordinary, everyday mortals as to constitute a new and separate species… transhumanism … (sometimes symbolized as H+) has been taken seriously enough by some as to warrant attention and criticism… [Francis Fukuyama] imagined that transhumans, with their heightened powers, better health, better looks, smarter minds, and longer life spans, would claim comparably outsize rights for themselves. But … there is already a wide variation in talents among members of the human race…” (Pg. 227-228)
He concludes, “we need to get at least some of our genomes and cultures off of this planet or trillions of person-years of work will be lost. We cannot assume that there is anyone at the other end to receive our radio broadcasts---or to replace us if we die… This effort to colonize space will benefit from engineering radiation resistance, low gravity resistance, and other such properties into our genome.. [But] we still have questions… Why and how will we teach our robotic or H+ descendants about emotions or morality? Which brings us back to the question, What SHOULD we do?... Hopefully this story … lays out a recipe (a genome) for a bold recoding of nature that emphasizes diversity and safety.” (Pg. 252-253)
Although at times this book may be too ‘technical’ for some readers, it will be of great interest to those studying genetic engineering and related topics.
