منذ فجر التاريخ، والبشر يتلاعبون بجينومات النباتات والحيوانات بتهجينها. وقد عرفنا الهندسة الوراثية منذ سبعينات القرن العشرين، إذ طبقت على تطوير المحاصيل والفئران المعدلة. إذن ما الجديد؟ ولماذا يتصدر تحرير الجينوم عناوين الأخبار؟
This book gives a detailed description of the following topics.
* Genome editing, gene drives, and CRISPR. * Synthetic biology and XNA. * Stem cell therapy and germ line vs. somatic cells. * Optogenetics. * Neoteny in dogs and humans.
This makes it worth a read. Be warned, the author exposes his blatantly unscientific opinions on the morality of the application of these technologies. The reader is constantly bombarded by what are essentially conspiracy theories and myths presented as though they were serious objections to potential use of genetic engineering in agriculture and medicine. They aren't serious objections. They're moronic ideas that don't belong in this book. I suspect the author may be relating them in some misguided attempt to share both sides of a controversy. If true, this is false balance and totally unacceptable. You don't put Intelligent Design in a book about evolution. You don't put alchemy in a book on chemistry. And you don't put anti-technology fear mongering in a book about genetics.
* The book opens by claiming that genetic engineering allows us to transform life "only limited by our imagination" which is obviously false. The limits to genetic engineering come from biology, and they are severe. We can't make flying pigs.
* Terminator genes are presented as a dastardly tactic to make money at the expense of farmers. In fact they were developed as a safety measure to assuage the unjustified fear that GM traits would enter wild plant populations. See the anti-GMO scam in action: (1) Make people afraid of contamination and demand the development of preventative measures. (2) Decry contamination-prevention technology as a greedy scheme. Pitiful.
* The author claims issues raised against development and use of GM traits are "not purely scientific". This is a deepity as it's obviously true for any technology, but certainly no more true for GMOs than for the printing press. Those "not purely scientific" (read: unscientific) issues raised against GMOs include incoherent ramblings about the "free market system", "public vs. private ownership", and "profit vs. sustainable agriculture". All of which are completely non sequitur to GM technology. GM traits are no challenge to the free market system. They do not change the status quo of public vs. private ownership, as non-GM seeds have been patented for over 100 years. They do nothing to change the tension between profit and sustainable agriculture. While this tension can exist, farmers don't generally manage their land for short-term gain. Of all people on Earth, farmers know the most about how to raise crops sustainably. It's their job.
* The author describes efforts to produce human-transplantable organs from pigs. He asks us to consider the moral implications of having human genes in pigs. Like somehow they would be partially human in some essentialist spiritualist sense. This kind of prescientific worldview has no place in medicine today where people die waiting for transplants. Speaking of morality, isn't it pretty immoral to even bringing up such a bizarre fantasy in what is supposed to be a nonfiction book?
* He outright states that transgenic changes should be employed with "more caution" than cisgenic changes. There is absolutely no justification given for this assertion and I assume it can only arise from a demented, prescientific understanding of what genes are and how they work.
* He says "there is still much that remains backward about modern medicine" and gives the example of surgery and chemotherapy. This is a dangerous thing to say because people do use such arguments to justify foregoing surgery and ceasing chemotherapy. Then they die of cancer. He was trying to make a valid point that compared to the medicine of the distant future, ours is primitive. Well, duh. But he says it in a way which seems to be designed to win favor with people who believe Alternative Medicine is an alternative to medicine (it's not). I conclude he either believes this himself (in which case he's a dangerous person) or is just trying to appeal to a wider audience with lies (in which case he's also a dangerous person).
* He bizarrely claims that germ line editing is more controversial than gene therapy. I believe he's uses the word "controversial" as a code word. That curing disease is a good thing is generally not controversial. Curing diseases in children is also generally not controversial. The only objections raised against germ line editing are unscientific or totally illogical. For example, essentialist ideas about human genetics remaining pure or irrational fears. He alludes to fears of a slippery slope towards eugenics but this is fallacious because we're not talking about eugenics. He also uses the word "consent" but doesn't really explain how it's an argument against germ line editing. Children don't give consent for any attribute they inherit from their parents, so this argument is an obvious non-starter. It's valid to mention the popularity of this bad ideas. But it's unfathomable to stop at bare mention and not take the time to expose why these bad ideas are bad. I conclude he either doesn't understand why they are bad, or doesn't believe his readers care. He's misleading his readers either way.
* He says that we shouldn't release GM mosquitoes in the fight against malaria because it "could have unpredictable ecological consequences". This is special pleading as doing nothing could also have unpredictable ecological consequences. It's also an argument from ignorance as it may have no unpredictable ecological consequences whatsoever. What's more, it will certainly have the predicted consequence of eradicating one of the worst human diseases! I think that's worth some fucking risk!
* Another one of those "controversies" mentioned is about the practice of deriving human stem cell lines from embryos. The only objections to this research tool come from the morally and scientifically unjustified belief that its wrong to destroy a human blastocyst. This bizarre belief comes directly from the religious idea of a soul and has no place in science or regulatory policy. This is how ideological propaganda operates. It gives mention to a "controversy" without explaining that moral and scientific reasons why it's complete and total bullshit.
* He describes techniques which might allow same sex couples to have their own biological children. He shockingly describes this as counter to "the natural order of things". What is this, the 20th century? Hey asshole, fuck you, and fuck your natural order of things.
* No joke, this chump makes reference to Oryx and Crake like it's some cautionary tale of what might actually happen in our future. You do know that's a fiction book, right...? He also references Jurassic Park like it's some cautionary tale about bringing back extinct species. Um...?
* The single most infuriating and illogical argument was an argument against the use of genetic engineering in medicine. He said that advances in medicine "mean little with social inequality" i.e. if you're poor you can't benefit from scientific breakthroughs in medicine because their application is out of your price range. (I expect those advances still mean something to those who can afford them!) This simply isn't an argument against scientific research in medicine. Social inequality won't be fixed by grinding the gears of scientific discovery to a halt. I firmly believe only a horrible person can be capable of making such an inhumane, evil argument. Even if he doesn't himself believe it, why give voice to such putrid moral bankruptcy as "stop science because rich people benefit most from it"? Even if this were my only complaint in the entire book, it would still be a 1-star review.
مدخل رائع لفهم تطور التعامل مع الجينوم تاريخيا و أغلب التقنيات الحديثة وصولا إلى المستقبل .. أين ممكن أن نذهب. الأمثلة مفصلة بلغة سلسلة تجمع بين القوام العلمي و الفهم المتاح لغير المتخصص بشكل دقيق بعلوم الجينات . ربما أحببت أن يكون الطرح الفلسفي و الأخلاقي لجميع هذه التقنيات و آثارها أكثر حضورا و استفاضةً مما هو موجود في الكتاب .
كتاب عميق ومتخصص جدا كعادة كتب السلسلة جايب الوراثة من جذورها وتأثيرها علي حياة الإنسان في مستقبله موضوعات شهيرة أصبحت معروفة مثل الطعام المهندس وراثيا هو واحد من موضاعات الكتاب
An interesting and mostly accessibly-written book about the cutting edge of genetic engineering. See my full review here: https://questionableevolution.com/201...
Many interesting examples, and correct as far as I can tell. But somehow the overall story did not really come together. I suspect that I will not remember this book very well.
