@@Meowthix Well you can't have something that eats everything unless you go with brute force, like a black hole. And maybe the most complex machine or bacteria could be able to do this. Even then, black holes still lose matter. So basically something that would eat glass wouldn't eat maybe plastic of some type of material. I think this is the future because this allows us to do things we are not smart enough to do already. For example there already exist a bacteria that consumes plastic. Fun fact, coal is just really old wood from trees at a time where no organism was able to consume wood, that's why it's underground. To me these kind of experiments are the very basis of our future technologies. Anything that is not renewable or polluting could be recycled using huge bacteria farms, using way less energy than any machine we could create. (It would be the same amount of energy technically but the bacterias would be able to also harvest energy from the sun, rain, air, e.t.c). But if all that is true, it would make it theoritically possible that everything gets out of hand. Like bacteria starts stripping all the atmosphere, than evolves to consume the crust. If the bacteria crap is simpler than what it needs to reproduce, earth could end up becoming a huge planet composed of only 1 bacteria, no elements. Or even revert back to hydrogen, making it a small star. I don't think we humans are smart, powerful and certainly not complex enough to be able to destroy life. Even if we manage to destroy 99.99% of it, the last human won't be able to find and outlast all bacterias on eath. Which would then rebuild life after the human dies. But that's my optimist view, I know most people wouldn't necessarily agree.

@ashurean
@ashurean Год назад
I think he might either have some familiarity with storytelling concepts, or just read a lot and have an intuitive understanding. Because the way he described both the two ways they expected the bacteria to evolve (one unlikely event causing it means it could've happened at any time vs many unlikely events leading up to the evolution means it couldn't have happened any sooner than it did) and how he described the differences between the Rectangular Hyperbola and Power Law models reminded me a lot of how the plots of stories play out. Maybe I'm looking into it too far, but the parallels sort of jumped out at me, and it would make sense that turning abstract data into a kind of story would be more appealing to a layperson. Regardless I absolutely agree with you, I was thoroughly engrossed watching this.

Multicellular bacteria would be so cool! And hopefully it would be vastly better at survival so the other bacteria would have to evolve to keep up. And then so on and so one. I guess the ultimate goal would be to evolve some kind of complex multicellular organism. Perhaps with organs like a brain, or something new and so far unimaginable. It might seem impossible in an environment like this, but we are here somehow, and that fact seems impossible too! Damn this stuff is so fascinating!

Not suggesting this is the case and such a hypothesis could be confounded by a systematic shaking of the flask but anyway, just a thought-provoking experiment/video all around.

I was imagining how would the team have reacted to the announcement of the covid lock-downs? I suppose, instead of the fear of contracting covid, they are probably thinking "oh, my germ experiment has to keep going!" Huge commitment, huge achievement, power of persistence + time.

I'm a huge plant nerd, and since I've gone beyond 50 plants on my 50 square meters, I've always been struggling with thrips infestations. Being less educated on both biology and botany than I am now, I first tried to get rid of them just by brushing them off and using household pesticides. The thrips very quickly adapted to the pesticides, so much so that I had to vastly increase the amount I was using to the point of drenching my plants' leaves so much that they became sticky and ugly, and when that stopped working (this is at most half a year after I started) I kinda just gave up and just brushed them off whenever I found them. Unfortunately, eventually, the thrips evolved to adjust to my specific plant culture, which is around 2/5ths succulents, so that's what they started to get a taste for, and at that point, their population exploded. I had gathered a little more plant parenting knowledge since then (especially just how important lots of light is), so my plants were generally healthier and stronger, but no household plant is strong enough to resist an army of thrips. I started using green lacewing larvae, which are the thrips' only (easily purchasable) direct natural predator, plus californicus nematodes both on leaves and in the soil. Applying four courses worth 250€ over three months got rid of most of the thrips, and since then I apply another two rounds (~75€ each) of larvae & nematodes about three times a year, which is keeping them in check. Being at just under 200 plants on still 50 square meters right now, I don't think I'm ever getting completely rid of them. It was deeply fascinating and awesome to see evolution and darwinism happening right in my own home. Botanically, it's also so, so terrifying. In most industrial countries, thrips especially are a huge problem, with not a single pesticide providing reliable resistance against them. As I could easily see in my own place, their evolutionary process starts adapting within months. Fortunately, the natural food chain is an obstacle darwinism has a much harder time to jump than environmental conditions (which I'd count pesticides under), so for now, I'm probably gonna be okey.
@kuldeepsojitra418
@kuldeepsojitra418 8 месяцев назад
This was really fascinating to read thanks for sharing. Currently I would say the thrips and their predators that you have introduced are in an evolution battle in your garden. Just as the thrips become better at surviving against the pesticides they also become better at surviving against the predators (at a much slower rate) but this time the predators are also evolving, making them a better solution to pesticides which don't really change except for the concentration and amount used.

The fact that bacteria can survive by being frozen and reanimated is the most amazing thing. How many dead planets must have bacteria just sitting there waiting for it to warm up again after millions of years or have bacteria that just hitchhiked on a asteroid that never burned up in an atmosphere .

That's the nature of research, you often times don't see the practical uses immediately. Heinrich Hertz is famously quoted as saying his discovery of radio waves had no practical application, just that he proved Maxwell correct. Yet here we are communicating over vast distances of empty space.

When Lenski started the culture of E.coli growing in his lab and since they reproduced so quickly, now they’re up past 60,000 generations and that’s like a million and a half years of human lifetimes. In his work he’s seen a lot of beneficial mutations come along but it turns out that the great majority of the mutations were in pre-existing genes and they either broke or degraded the genes. So the bacteria were evolving or improving more by devolution than by evolution. Darwin’s theory needs to show that organisms can improve by building things, and that what has been missing in this terrific experiment. This E.coli experiment shows that trillions of random mutations are not capable of building anything new. By the numbers this E.coli experiment is giant but it’s dwarfed by the size of a natural experiment involving humans infected with malaria. Every year about a billion or so people contract malaria so that’s a billion times a trillion cells that are made each year on the planet. In recent decades scientists have exhaustively studied malaria they’ve seen how it evolved resistance to several of the drugs used to treat it but what is more interesting is what scientists haven’t seen. There were no new molecular machines, no new genes, and yet it had so many chances, evolutionary theory would’ve predicted that you’d get something really pretty impressive out of that, but it wasn’t seen. This raises a serious red flag for evolutionary theory. The discovery that many beneficial mutations are actually destructive or degradatory mutations puts a huge monkey wrench into Darwinian theory. Not only can’t Darwin’s mechanism of random mutation and natural selection build complex systems, it has a strong tendency to degrade them. We see that overwhelmingly the good mutations come about by breaking old genes. So you’re not making something new you’re throwing out something you already had. We see it in bacteria we see it in mammals we see it in birds we see it everywhere that’s been looked at so far. This evidence completely conflicts with evolutionary theory. What’s funny is Lenski set out to to try to prove the creative power of mutations and natural selection only to discover that it doesn’t have any creative power at all. The fact that this video fails to mention this is beyond me. There needs to be a radical rethinking of this Darwinian paradigm. Darwinian ideas are so entrenched in our culture that it will take time for things to change. Scientists need to start following the evidence where it leads. The view that mutations are our creator, not God, is the view most leading scientists favor. It is a worldview that supports the idea that humans, and all life, are the result of billions of genetic damages caused by carcinogens and other poisons, not an intelligent creator. This view is not only irresponsible but contrary to observable fact.

@@TyrellWellickEcorp Thank you so much for responding with appropriate level of attention to detail, it is right up my alley of communication style and really appreciate you taking the time to comment. I am actually in the process right now of putting a project together with examples of extremes at both ends of nature's pattern of moving targets. I have the one extreme of what Society thinks is the Pinnacle of germs on this planet, which is the human being "living the life". Basically the ego end of what my project is trying to represent with this model, Kim kardashian's, fame, celebrity, rich people and the illusion of happiness. And then at the other I have an endless list of patterns that I have floated over on to one another so many times that a common denominator has revealed itself in ways to achieve what people think they want in ways that are actually healthy to the other end of the spectrum, which is why I researched bacteria in general and was happy to see this new video. And your comment definitely brought clarity to it and agree as to why what you had mentioned would not be more of a focal point when discussing such topics. Much of my research from pattern synthesis has also confirmed what you seem to be suggesting, that the paradigm needs a shift in order for the other patterns to line up to respect the original pattern, which is what kind of like the Tower of Babel having divided languages so there is too much lack of communication for any real progress to reach the heavens too quickly. I have been taking notice of pattern after pattern revealing what people call the cycle of life, but I kept having the sneaking suspicion that it was not the 2D linear model that people are relegated to observe such research. Kind of like balance is not on a left to right scale although that clearly is also balanced, meaning it's true, but it's not as true as a wider context showing a classic game such as topple, if you've ever played it. Which is also now more true than the first example, but I'd say a g meter in all directions like in fighter jets accounting for yaw and pitch and velocity are the most accurate depiction of balance compared to the more rudimentary image of a classic legal scale. And I suspect the same goes for what you are alluding to here, it's not that the cycle of life is this simple thing to understand, not sure why anyone thinks these topics would be simple, they literally require endless conversations of confusion in order to get anywhere, like a healthy *RELATIONSHIP ideally does on purpose. I see a pattern in the form of giving the devil his due, so to speak simply, by recognizing it is not a devil at all, but another pattern I am floating over here now is from someone quoting "you know what you do want when you know what you don't want", so it's a sense of throwing out something that you once wanted in order to experience the gratification in a Way beyond even you could think what you originally wanted would bring to you, which is now floating over to the pattern from the quote suggesting "you cannot solve a problem with the same state of mind that created it". So to synthesize your model within the confines of a RU-vid comment, what I am planning on using it for is to emphasize, it is not about avoiding making mistakes, it is about efficiency, and shortening the gaps between from which you need to spawn new generations because of unnecessary mistakes, you will always be throwing something out, you will always be making a sacrifice, but you get to choose your sacrifice in a healthy environment, and a lot of people's problems are deeply rooted in the unhealthy environments of their minds, which breeds unnecessary pain, in a world of inevitable tragedies, their lack of full contribution makes it hell on earth, which now floats over to Spider-Man logic, "with great power comes great responsibility" lol... Did I say the same thing you did in different words? ;)

As a human biologist, I think there are also astonishing examples of rapid evolution in humans. To give an example, a mutation occurred roughly 20 000 years ago in Europe which made people lactose tolerant. Since lactose tolerance supported survival during repeated periods of starvation, it rapidly spread to different populations and contributed to greater population growth (I made a video about this ). This mutation was so successful that we can find it in the majority of all people of European descent today!

Why are you and everyone else that does this so astoundingly dumb and ignorant? Do you have such a disturbing need to look smart that you do stuff only idiots will like, which always gets a lot of likes because there's so many.

The reason i find it contradictory is because if we push the theoretical always-improving model to its logical conclusion, then the rate of growth would exceed what should be chemically possible and would eventually reach infinity, which shouldn't be possible, though this doesn't necessarily say anything about new breakthroughs so i do suppose it is possible to continually improve within finite limits??
