Did no one watch Jurassic Park? You can't put genetic alterations in the environment and expect them not to propagate. The idea that this is possible has been proven multiple times to be utterly and completely false. No matter what the level of care or control. You put it out there, and there is any possibility for it to proliferate... it will proliferate. Period. People don't learn they still think they are in contr…

If you're citing Jurassic Park as your source, I'm not sure how persuasive the argument is.

I believe that study was peer reviewed by Roger Ebert.

Edit: off topic, but I just read that review from 1993 and it was pretty good - https://www.rogerebert.com/reviews/jurassic-park-1993

Hey. In the poster's defense, they stated specifically the downside of hormones was you had to treat every breeding location, which consists of every puddle or stagnant body of water, which includes the necessity of synthesizing and delivering the hormone to every candidate breeding ground. The idea behind the gene manipulation circumvented that logistical challenge since the males would do that job anyway. My major…

It's a touchy subject for me because I try working on it in my spare time. My point is this, in Florida, there's a shitload of policy, gov action and procedure to keep mosquito populations at a minimum. It use to be spray trucks were a weekly thing when I was a kid in the summer (90s). It's not that way anymore. In most cases, mosquito populations are no where near as bad compared to when I was a kid. Mostly. It can…

The issue is there is a big difference between Florida and Africa.

Think about it. That hormone spray gets synthesized somewhere(on the same continent), loaded onto trucks (which are fueled, from gas reserves that are themselves kept constantly supplied and properly mixed, (by power generated somewhere else and delivered by reconstructed and maintained infrastructure(kept working by so on, and so forth, and so on...))),

There is a LOT of advantages that the U.S. has in regard to that sort of logistics. Not all of that may necessarily apply in Africa such that fleets of large capacity tanker/sprayer trucks filled with hormone solution can be trivially mobilized.

That's why this genetic shtick was so attractive. No trucks needed, no fuel or solution airlifted. Just a bunch skeeters that do all the hard work of getting the fix where it needed to go.

It was honestly looking too good to be true but also suffered from being too good not to try.

I can't find the papers, but larvacides are not normally field used in trucks. They're usage is 1-2 gallon per ground acre with a dude wearing a hand pump backpack sprayer and when used in water, are dispersed by small row boats. Each area of the water is tested for concentration of larva and given the body of water and amount of larva found, a dosage is implemented. Now, that's not to say they aren't used in airplane dusters and in trucks as well. But that's not the main method of delivery. There are people in small outboard motor boats going through the Florida swamps putting this stuff in.

And yes, we do have a lot of great infrastructure in comparison. Fully aware of this. This doesn't mean that Africa is full of invalids that cannot adapt and overcome. Plus, don't think Africa is just some paleolithic continent. They do have industry and infrastructure. Not to western levels. But it's not all mud huts. But if aid money is going to be spent on combating mosquito borne diseases in third world countries, I want to see that money actually working for long term results. I'm fine with testing new methods. There's nothing wrong with that. But people keep jumping into these silver bullet schemes and ignore the tried and true methods because it's "antiquated". What I hate seeing is the public seeing these unicorn fart projects and thinking "There's the solution, no need to do anything else we've been doing." Because then policy makers think the same bullshit. And sadly, I'm not exaggerating. Whenever these pop up, comment boards always ring up "Why aren't we shoving all the money at this?". Because it's fucking stupid. That's why. The basic math doesn't even work in their best case scenario. And, I've said it elsewhere, I'm no mosquito expert. This is a side project/passion of mine. And I predicted the exact outcome after most of my knowledge stemming from a weekend reading papers and gov based mosquito control history (it's actually a ~100 year old scientific endeavor with a really rich and fascinating history, to me at least). But if a total dumbass like me is able to know what's going to happen and why it won't work, come on, seriously? I'm the first one to say, I'm a moron. But if I'm smarter at this topic than these "long time researchers", wtf? Caveat, not to say there aren't a lot of amazing entomologists out there doing great work. There's plenty. But I don't want to see half-ass-shitheads getting the money and glory compared to the real entomologists who are legit in making a real effort to leaving this world in a better way than how they came into it.

The genetic shtick is so attractive because it's sexy and lazy. That's why. Take a million bucks and you get to pick work in an A/C lab to make genetically modified mosquitoes that have a slim chance (at best) of working or buy half a million dollars worth of larvacide, go out into the heat of Africa/Asia/S. America to teach people how to test and apply it, and if any money is leftover from travel/manpower/etc, spend time in a hot and dangerous 3rd world countries to setup either small scale infrastructure projects or edu facilities for long term results. It's not hard too figure out which most people will gravitate to.

The only lessons to be learned from Jurassic Park are a) Michael Crichton is a better writer than people think b) Wow, this CGI thing is going to be huge! It's fiction. It did well because it tapped into the zeitgeist and gave form to people's fears. It is not evidence that those fears are justified.

> It is not evidence that those fears are justified. ... until now Crichton did not created his novel from zero. Was after talking with a lot of scientists, taking several scientific theories and facts, and using it (more or less embellished for literary and fiction purposes) to build the book. Only because it appears on Jurassic park does not mean that the subjacent idea is incorrect (neither the opposite of course)…

> ... until now

Nope, it's still not evidence. The fears may well be justified, but simply appealing to the fear itself is not a good-faith argument. If you think Jurassic Park was based on solid science, fine. It shouldn't be hard to marshal it to make your case.

Enough people said this was a bad idea to expect this outcome.

There is no evidence of harm yet. There are only a few mosquitoes with a bit more junk-DNA.

It's not about evidence of harm, its about evidence that the safeguard didn't work.

Imagine I was demoing an elevator with a backup stopping mechanism that kept it from going into free fall. So I hoist the elevator 10 feet up and cut the line, and the mechanism doesn't work, it falls immediately to the ground.

Would it be reasonable for me to say, "Nobody was hurt, the elevator only dropped 10 feet, so there's no real problem"? I would want the elevator sent back to design/engineering before I was willing to put any people on it.

The mosquitoes were not supposed to be able to breed, and they did. Not being able to breed was the safety valve. In this case, because the modifications were very minor, the effects of that are pretty minor, just a tiny bit of junk DNA. Because the rollout was small, the effects are small. I only hoisted the elevator 10 feet.

But before we doing larger rollouts or more sophisticated modifications, we should make sure that our safety valves actually work. I don't think it's unreasonable to ask that we collectively prove we can get small things right before we start doing large things.

Despite this failure, I still think the species should be targeted for extinction. What are our options?

I really want to ship some software tomorrow morning to all of my clients, but it might have critical bugs that corrupt their existing data. What are my options in that scenario?

The best option if you really want to wipe out mosquitoes is to invest the actual time and resources required into proving that mosquitoes can be targeted precisely, and that there won't be knock-on effects.

People get angry about that answer because that's not fast or convenient, and in the meantime people are dying of malaria. And I really do understand that, but there is no fast, easy, safe way to eliminate a species. Every possible solution takes time. I'm sure my boss gets upset too whenever I tell them that the new database upgrade needs to go through QA again.

The short answer is if you want to help people with malaria today and not just theoretically help them in the future, you should invest in building out Africa's infrastructure and increasing medical access and standards of living for the people who live there. That's also a pretty difficult task, but it may end up being faster, safer, and easier than eliminating mosquitoes.

Maybe we are not discussing the same hypothesis.

null hypothesis: "We can put genetic alterations in the environment and expect them not to propagate" or if you prefer:

"Modified mosquitoes will never, ever escape and reproduce, because we are scientists, really smart, we know what we do, etc"

(Modified mosquitoes escape and reproduce)

Null Hypothesis is false, and Crichton is still a rich man. Next question.

And presumably all the birds will have plenty of other things to eat, right?

Aedes aegypti is not native to Brazil. Aedes aegypti propagates dengue, zika, chikungunya and yellow fever and is a big problem in Brazil. It kills people (and other animals). Just this year, 600 people died from Dengue alone in Brazil, and almost 2 million of people infected with it, and is not even spring-summer yet, which is where is the big problem....

I was discussing the comment I replied to - "Did no one watch Jurassic Park?" It's a good movie, but things that happen to imaginary scientists should not guide our decisions about real-world experiments.

I think the hypothesis of the experiment was something like "these genetic modifications will prevent mosquitos from reproducing". We know that the mosquitos did reproduce because the scientists deliberately included other modifications that would be easy to detect, and monitored the mosquito population to see if those genes showed up.

Contrary to your "we're so smart, we know what we're doing," caricature of the arrogant scientist, they made a hypothesis, carefully designed an experiment to disprove it, carefully gathered the data, and published a paper showing that their hypothesis was disproven. This is how science works. It doesn't mean that what they're trying to do is impossible, only that this approach didn't succeed.

How wrong am I to draw the conclusion from this, that people claiming that GMOs are "completely safe" (i.e. cannot have unexpected side effects, such as creation of super-species that completely crowds out other, non-GMO and now inferior, species in the specific niche, or the migration/expression of toxin-producing genes in unexpected places) are full of bullshit? That's my knee-jerk conclusion, I'd be really interes…

I don't whether they are full of bullshit or not, but for the life of me I can't see how this particular example demonstrates they are full of bullshit. They made a genetic mod that was supposed to prevent them from breeding. They got it wrong and they breed. Far from producing a super species, this modification weakened the offspring and will be eliminated from the gene pool over time by natural selection. It's hardly a super organism.

This is pretty much true for any modifications we've made. They invariably have a the same effect: they enhance fitness in some circumstances at the cost of reducing in others. For example round-up ready definitely gives you an advantage when there are hominoids spraying round-up everywhere, but at the cost of some energy efficiency. If those hominoids disappear the advantage gene gave them will disappear but the disadvantage will remain, and consequently gene itself will disappear along with the hominoids. The vitamin A enhanced bananas do very well when those same hominoids knock off all their competition because their want that vitamin A, but when the hominoids disappear and they are back on an even footing with their competition and they won't fair so well.

I could go on, but it's pretty much the same story every time. Natural selection has already produced super organisms for every niche. Think the blue whale, which is the largest animal every to roam the earth. It looks pretty "super" to me. We can alter the genome to be work better the situations we create, but when those situations vanish the situation the super organisms natural selection is so good at creating will take over again.

The implicit assumption in the super organism argument is mankind is so superior we will be to bring more intellect and computation power to bear on creating super organisms in a few decades than natural selection has over millions of years. The proposition is laughable, and it's the height of hubris.
