Using CRISPR To Resurrect the Dead (cnet.com) 121

One of our most powerful tools to fight biological obliteration is CRISPR, a burgeoning gene-editing technology that acts like a molecular blade, slicing DNA apart and allowing us to add and subtract genes at will. It's now being used to combat invasive species, destroy antibiotic-resistance bacteria and, controversially, edit the genes of human embryos. From a report: In fact, it's so exceptional at editing DNA that "de-extinction," the process of bringing extinct species back from the dead, is on the table. Science has already unraveled the DNA code of long-dead species such as the woolly mammoth, the passenger pigeon and Australia's iconic Tasmanian tiger -- and now, pioneering researchers are using CRISPR to remake modern-day descendants in the image of their ancient counterparts. Could we transform an Asian elephant into a woolly mammoth? We are marching toward that reality. "The CRISPR revolution is the whole reason why we've been having these conversations about de-extinction," says Ben Novak, a biologist working on restoring the extinct passenger pigeon.

There are opponents of de-extinction, however. They point to our responsibilities with species already living on the edge of extinction and ensuring we allocate resources to save them. Others are concerned about the ethics of resurrecting ancient beasts and how they might fit into current ecosystems as the planet chokes under the heavy cloud of climate change. In this era, as the planet warms and biodiversity plummets, we're faced with a question. Should we resurrect the dead?

          I don't think limiting our expansion and influence is the same as disassembling civilization.

          • I am for the complete Trantorization of Earth. Why? Because I love humanity and the little guy and want a hyper-advanced civilzation where even the poorest live better lives than presidents and billionaires do today.

            This is neither a joke nor a troll.

            • Trantorization is probably a bit extreme... and unnecessary.

              Assume the earth's land area is approximately 58 million square miles.

              Assume 50% of it is either under glaciers (too hard to build on) or set aside as wildlife reserves or parks.

              Assume 25% is used for farming or heavy industry. That leaves us with approximately 15 million square miles for urban areas.

              Of those 15 million square miles, assume:

              * 5% is developed to the approximate density of Singapore (20,000/square mile)

              * 20% is developed to the appro

      • In short the most responsible and effective thing we as humans can do is to limit in reverse our expansion and influence, allowing the planet to rebalance itself overtime by natural process

        An alternative, which is far more in line with how we have always done things, is to find ways to reduce and even eliminate the impact that out continued expansion and influence has on the natural environment and to find ways to expand beyond our planet. CRISPR offers very interesting possibilities for designing custom organisms to sustain human life on e.g. Mars and possibly even terraform planets such as Mars and (if we can get anything can live there) Venus.

      • None of this is true. The most responsible thing we can do is continue advancing technology rapidly.

        You can less predict 2100 than people in 1900 could predict today.

        For example, robots could rip open landfills and sort the goldmine for recycling. Bernies of the day will probably scream local cities aren't getting their money's worth from bidding contractors.

        We will produce 100x the energy of today, and more cleanly and cheaply.

    • The world doesn't need our solutions it needs our discretion and self-restraint as a species.

      Totally agree, which is why this is important. Most large animals (i.e. megafauna) are extinct because of humans. Bringing back the European lion, the woolly mammoth, or the Tasmanian tiger is just hitting the "undo" button on actions we took in the past. Drawing the line at "things we hunted to extinction" makes sense to me.

    We'll use technology to bring Wooly Mammoths, Sabre-tooth Tigers, Dodos, and T-Rex back from extinction. Zoos will have lines miles long. Then, after a while, people will just get bored.

    Eventually, it'll become more profitable to breed all-black 40-pound tigers and purple-feathered 2-pound mini T-Rexes as exotic pets, and the originals will go extinct again (possibly, with little interest in preventing it, since people will figure we can always de-extinct them again).

      • Is there any real evidence that T-Rex even HAD scales, as opposed to feathers? I thought the current consensus was that T-Rex looked more like a humongous ostrich than any modern reptile.

        Which ironically, brings up reason #2 why people will get bored: big flightless birds aren't particularly scary... at least, not behind 2" laminated glass at a zoo. In fact, I'll go out on a limb & predict that long before de-extinct'et T-Rexes appear, we'll have 100% designer large reptiles made to look like people THI

          • Errrr... I think you misread the sentence, and missed the very important second half. I didn't say we'll make dinosaurs that "LOOK LIKE PEOPLE", I said we'll make dinosaurs that look the way 'people THINK dinosaurs were supposed to have looked like'. If you stop reading the sentence at the word "people", you'll completely misunderstand it.

        • Birds have both feathers and scales on different parts of their bodies.

          Feathers, like hair, evolved from scales.

      In Jurassic Park-the book, not the movie-Hammond got his original round of funding by showing a 2 ft tall elephant, a perfect pet size-but also ill tempered so not suitable as a pet(it also was developed through selective breeding and similar techniques, not genetic engineering). In The Lost World, Dodgson talks about wanting to reverse engineer the Ingen technology to develop, among other things, miniaturized pet dinosaurs (who are also genetically engineered to only eat food produced by his company for a

    Your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should.

  • Me, I'm just looking for a 'dodo omelet'.
  • I am actually OK with doing a lot of things with CRISPR to make lots of better organisms.

    However the idea bringing back extinct species in the way talked about here I find kind of bothersome - mostly because it's not really them, just kind of a dressed-up elephant or whatever. Seems a bit cruel to bring an animal like that into being that its own kind might easily reject, and there will be very few (if any) of its own kind around.

        FTA, it appears they are going to change Asian Elephant genes, and Using CRISPR, change them to Mammoth and use an artificial womb.

        It... might....just... work, if they use blockchain as part of the process.

      More likely we'll produce a mammoth that bears only a passing resemblance to a mammoth since DNA isn't the only thing an offspring inherits from its parents. I'm sure that in an artificial uterus, you could approximate the various environmental factors that affect gene expression. I hope they'll let me know when they have one of those. Which is to say nothing of either the cytoplasmic junk or the microbiome, which we're starting to realize is pretty damn important, although we have almost no understandin

    The real question are early humans. Neanderthals, or some of the stuff in-between modern humans and apes, that probably is too smart for a zoo and too stupid for general society, to say nothing of mates for them.

I've always theorized that some of the Neanderthal and Homo Sapiens hybrids got the best of both worlds. Neanderthal, quite likely had a larger ocipital lobe, which may have lended to better visual/spatial memory and reasoning. Whereas, Homo Sapiens likely evolved higher forms of communication which allowed for greater collaboration. Mix those two together and take the cream of the cr
