Hello all! Hope you are enjoying the video. Quick correction - the image of frozen Earth does indeed hide the shape of North America. Oversight on my part. Obviously wouldn´t have been under there back then! Apologies.
This video starts out very good, but then ends abruptly. you want us to believe in the evil snowman that killed the earth?? then why don't you tell us how he was killed, as if you are not blind, but look out the window, he hasn't been seen for billions of years. Or is this video just a blathering cartoon?
I was just preparing to comment on the point in the video at 24 minutes that shows the current outline of eastern North America that would have been erroneous to the period in discussion. Glad to see your comment, but wondering about your editing process.
Its a frozen planet people !!! I can see gilligan and the skipper there if i look close . Do you realize you should be listening more and looking at the pictures less. lmfaro Its all "the deep state" fault , that put monsters under your bed .... and nuts in your education.
John McNulty. Even anaerobic bacteria with metabolic pathways , with the ability to self replicate asexual still is making it a very complex process, not by accident. If asexuality was first, then how did a male/female procreation, come up into existence separately first on their own by accident? And then somehow meet up together after having come into existence separately by accident with the right biological micro machinery? Ignorance is at play here in people not knowing any better making them an easy target for misinformation in the assembling of atoms and amino acids at the molecular levels. Having the right machinery with matching parts, in order to exchange the correct genetic information or coding , by accident is a problem insurmountable by biology alone? This is a very, very, very , very complex process. How was all of this, by ACCIDENT? It wasn't. === Evolution = Self Assembling Atoms Impossible =====
Most of this I've read or heard before, but the realization how fragile life really is, shocks me every time. We're living on an unimaginable graveyard of billions of wiped out species. Think about that.
Imagine if something evolved a new metabolism and dumped poison in the atmosphere and we all perished within a decade with no way to economically fix the issue.
@@needlesandsonics5819 We are the only thing capable of caring. You are right of course but your argument is best made from the perspective of something that is already dead.
The only people that are angry are those that let their sins interfere with their science. I only trust Christian scientists because they have minds that are more open to the whole picture. This video is silly and nothing but ridiculous and worthless lies.
discovery channel used to be good when i was a kid in the 90s. but now it is what it is just like more other things that are what they seem to be, utter crap
Yes. Discovery was a good idea that was quickly turned into a needed money maker by the bottom-line people. Pre-internet/TH-cam/ etc. that was sadly predictable.
This sounds so much like a made-for-TV documentary. I've seen a fair number of long-form educational videos on TH-cam, and none of them made me feel like a kid watching the Discovery Channel the way this did.
More like being FOOLED like a kid...He was doing good, until he tried to tie the Co2, to the destruction of methane...Which, is made up of Co2...Doh! 21stcenturywire.com/2020/09/05/global-cooling-noaa-confirms-full-blown-grand-solar-minimum/
One thin that might' ve happen is that you would get oxygen toxicity.Luckily we could just get something to counteract it (like a breathing apparatus) to return it to normal levels.
The concept of 2.4 billion years ago is difficult to imagine. That we are lucky enough that this blue planet has been safe for this long is hard to believe.
This little green planet hasn’t been safe for 2.4 billion years.. it’s like you forgot about the most well known event where an Astroid hit earth and killed 70%+ of all life being the end off the dinosaurs. Literally a few 100 meters bigger and I doubt anything would have lived.. people don’t realise how fragile our existence is all it takes is a 1-2 mile wide astroid and humans will be gone
What if what we're doing to the planet now is comparable to this? We'll wipe most of ourselves out, over and over again in cycles, until some of us learn how to survive our own waste products... but then we'll be free to waste the rest of the life on the planet, and only the tiny fraction of life that can survive that newly transformed world will go on to populate it in the distant future.
@@Pfhorrest Its not though. It's not comparable. Humans are not effecting climate to the level of causing extinction events or ice ages. The earth goes through cycles mostly driven by our own star. Our magnetosphere is weakening more than ever and all it takes is the right CME to create another Carrington Event. No electricity for some years after that. Also we are on the cusp of our stars cyclical micro nova event. This is real mass extinction. Imagine hot pieces of ejected plasma from the sun impacting around the world and much much more. Do you think Bezos is flying to space for fun? Elites know what is coming.
More like spellbinding. All freemasonic occult lies using gematria to place spells over the subconsciousness of the drugged/pharmekia human mind. Wake up! Demon/reptile worshipping humans run the world. G in freemason = 7
It is mesmerising! It gives my scrambled brain cells something to focus on. I’m thinking of it as a history lesson everyone needs to watch, because now we are the microbes!
It's interesting to note how amazing and powerful photosynthesis seems. Like when we think of plants (or algae, etc.) it's almost magical, because they generate energy and grow without needing to harm other organisms (directly anyway). So it makes sense that when this process first started evolutionarily, it was extremely unstable and TOO powerful and sort of got into some cascade effects.
Plants may make simple sugar through photosynthesis, but make no mistake, plants need dead things to get the nutrients to grow. You can't put a plant in sterile soil and think it's not going to die. Not to mention, there's around 750 different species of carnivorous plants alone, nevermind the thousands of parasitic plants like strangler figs that directly harm other organisms as part of their life cycles. Life feeds on life.
I suppose it depends on how you view power. It's pretty amazing but considering how long photosynthesis has been around you would think plants would develop better ways to avoid being eaten. Perhaps that in itself shows the limitation of what plants can do really, they can make their own food but not defend it, at least not from other creatures which can move and consume.
@@Anotherguy1st “Defense” is the product of a scarcity that plants don’t really deal with. Because they get their energy from the sun, plants don’t need to defend themselves; they make more of themselves faster than any animal could ever eat them, and most plant species don’t really come into conflict with other plants. Not to mention that in many cases, being eaten by animals is to the plants’ benefit. You can bet that if it were efficient, plants would defend themselves more actively, but often they just resort to passive measures like thorns and needles. What does it say about power that it’s more efficient for plants to make more plants? That no matter how many die, there will always be more, like cutting off the heads of a hydra?
@@Anotherguy1st Plant do have defense mechanism even against animal. They release toxin when they detect they are eaten, to reduce digestability, mess with the herbivore metabolism, or straight up poison him, a shit load of psychoactive substances like caffeine or nicotine are actually insecticide produced by plants. And there is also torn and spine, those are defenses too despite being passive.
It’s amazing what humans have been able to learn and accomplish in a very short period of time. I’m always blown away by the fact that the earth has lived billions of different “lives”.
The first few videos I saw of this channel I assumed were taken from somewhere like the discover channel, I couldn't believe and am still amazingly impressed that these videos are privately made! I'd just like to say thanks this content is golden and I'm actually learning something about the ancient world compared to other docs that only focus on the popular events, incredibly well made my friend!

The difference is that, although not flawless, these people use actual science as opposed to the Discovery Channel, which is only interested in entertaining vs. educating people...nice work!
This here is a hiddem gem. One of the absolute finest channels. I did not know just how massive those changes were, it sure gives a whole new perspective.
It's humbling, in my opinion. Just to be here now, in this moment despite the current state of affairs....I feel lucky to exist. Like I was gifted something truly sacred. Idk how many people can relate but still.
@@sandiboots123 In the neighborhood of 4000ppm in the Cambrian ca 500 Ma. to a low of 180ppm Quaternary glaciation (which by the way caused a considerable die-off) which is nearing the cessation point for photosynthesis and O2 generation. Of course the IPCC won't tell you that as they push for that level. They also don't tell you what happened during the Eocene.....life bloomed, new species (especially hardwoods), etc etc., very warm and high CO2 levels far more than today.
The big difference is the time it took for big changes during these mass extinctions. Now we have concrete pouring across all areas, all forests and high diversity zones being choped and hunted down. Yes carbon levels may have been higher many years ago, but we are destroying the basic chains for any ecosystem to survive with no time to adapt. The thing was not only about CO2, it is about our disgusting consuming practices with no regards for others, we must be fficient in the way we obtain and protect the natural resources, and we already failed.
What a fabulous work. As always, your video felt like professionally produced documentary. From writing to narration and visuals, it's a work of art. Thank you for educating us and letting us enjoy it for free.
And most importantly, the science behind it. I have known bits a bobs about many of the facts presented but never thought to look at its entirety the way this video summarised it. Very well done.
The writer who came up with ice "...spreading like freezing corruption..." is a genius. That's a brilliant turn of phrase: well-stated by the presenter too! Cheers!
@@alexanderSydneyOz Without presentation skills, the most brilliant scientist will neither reach nor sway anyone, even if they are demonstrably correct in what they know.
@Controversial Chris because of your comment, I looked at his channel. Lol, looks pretty cool. I've never thought of exploring a lot of tubes. Thank you.
Excellent! I've learned a lot more about the process - which I had a very vague idea of. Superb narration punctuated with timely pauses which leave the listener hanging on every word. Thankyou!
The asteroid that caused the K-Pg extinction event 66 million years ago was *not* "80 kilometers wide". Most authoritative estimates place it between 10 to 16 kilometers wide.

It was only 3.7 inches. The jig was up after the angry ex started gossiping that the previous measure of 16 kms was a charade to gain academic clout of researching an "important event".
It amazes me how many things had to happen for us to be here. Makes you wonder if any dinosaurs evolve to the point where they had intelligence. We can't get DNA out of them so we wouldn't know or maybe would be DNA we didn't even recognize or know what did at the time. There was even sci-fi shows based on this theory.
@DuckDodgers. Butch!! Lmfao yeah Porky said the book didn't work and the mother said maybe you didn't use it right and spanks the baby with it. That was awsome!
@@BJETNT nearly all animals with complex enough nervous system have certain level of intelligence, I believe dinosaurs ain't so different. Did they developed some kind of civilization? That's another kind of topic.
I’m a geologist and really didn’t get much more than a refresh from this video. However. You got me to watch the whole thing. Incredible video. Very good science communication
Curious. Historians I have met consume media related to their specialization with vigor, even if it is 'just a refresher.' On the offchance you read this, do you do the same? I cannot claim to be a scientist, merely an interested soul who loves learning new things and looking at old knoledge in a new light. I earnestly wish I could spend my life wandering the halls of universities, thinktanks, research facilities, archeological digs, and the like. This world of ours is so utterly beautiful, so rich in wonders, I am always in awe. I live for sunrises, for new discoveries, and yet, a good refresher every once in a while does me a solid boost. My father was a geologist, taught me many things. Showed me how interconnected everything is. My own interests lead me to electronics, but every once in a while, I'll find myself staring at a hill or a mountain and think to myself, "What's in there? How old is it?" I've only traveled a little, but what I have seen will last my life. The Bighorn Mountains hardly deserve the name compared to the Rockies, but even so, standing atop them gave me a sense of scale that simply took my breath away. Standing atop Mt Hood a few years later gave me a sense of scope that I simply cannot put into words. Somewhere in one of my footlockers I have some fist-sized rocks from my travels. Rocks gathered from the St. Laurence River, red and white stones fron the Bighorns, granite from southern Oregon, even some Obsidian from multiple sources. Each one is a story in and of it's self, each ranging in age from a billion years to only a handful. It is a sensation of itself to hold one and think, "where did this come from?" Hmm. I think I need to get back out there.
@@Deridus Don't ever eat magic mushrooms and explore nature. You'll be ranting and ranting nonsense for paragraphs and paragraphs. I'm not a geologist, historian, or scientist but your shite talk made me respond. Be curious. It's great. Keep it to yourself

Not only that, demise itself was the foundation for future successes. We search for complex alien life but life itself is an unending chain of failed attempts and fateful recoveries. What are the chances for a similar outcome? While greater than zero, I'd say it's incredibly improbable. The Universe is not teeming with life in spite of fat chances for life to appear. That's simply not good enough. Life constantly needs catastrophe to recover from and also evolve further. Without any failings, life will wither away when the inevitable tragedy will come. Thus, the meek will once again inherit the world, unless even they are too proud facing their doom.
Demise? Decimation? Destruction? 'I don't think so, Tim'...Success breeds more success. Selecting out any life that is unable to adapt quickly enough. Is that what you mean?
@@alexandragamingronyno2275 I'd argue against that, success can come from catastrophe. We survive because the earth was terraformed but if we keep convincing ourselves that using the abundance of food an energy from that is wrong to do so, we will expire ourselves and from that, birds would probably rise. Chemistry has a few likely outcomes and things keep evolving in relatively predictable directions, especially where a medium like water, Co2, nitrogen, sulfur, heat etc are concerned. If you want to see what happens when things stop succeeding, look at sharks, they never failed so they never adapted and they never changed now they're as dumb as bricks and die if they sleep too long :p
Harold Burrows - "success breeds demise" Success? You mean like the mining of fossil fuels? The internal combustion engine and mass transport? The improvement in living standards (well ... for humans)? The Internet? Population expansion beyond the proportions of any other animal ever? Those are the measures of success - and they could *_never_* lead to demise .... could they .... ? The dinosaurs were here for 300 million years. Cockroches have been here for 400 million. We have been here for about half a million. There have been species far more successful than we are, and now, there's not much of a trace of them. Who will last longer - us or roaches? Roaches have a good track record. Primates ... not so much.
@@rhedinrage1601 i dont think an animal living for 400 million years has failed in any way so what it might be dumb but how far ahead are we intelligent wise? Id say only a tiny bit concidering AI and superintelligent aliens (which are most likely technological beings that have evolved from biological ones). Every step in evolution is necessary for the next one to occur for if a ladder was missing one step you wouldn’t be able to get up
its the amount of time that gets me. the extinction of the dinosaurs took 30,000 years! some of those iron layers took hundreds of millions of years.. and we are out here freaking out over the shit going on during our measly 70-100 year long lives. 🤯
@@missengineer2782 Makes me wonder if there really are any more technological civilizations in the galaxy. How many crises did we just squeak through in the last 5 billion years?
"Ha ha! Stupid bacteria... imagine poisoning your own atmosphere out of greed and killing everyone including yourselves because of short sightedness! Sure glad we have brains to prevent that..."
Exactly. The *planet* will survive whatever we humans throw at it. But whether we leave it habitable for the life that currently lives on it, is another matter entirely.
Accidentally stumbled on this channel, this was the first video I watched, and I immediately subscribed. Excellent quality overall, well structured text, wonderful narration and very appropriate video. So refreshing to have the information delivered in a laconic and informative manner, without the usual filler blah, blah, blah, mixed with dramatic pauses, distracting music and useless sound effects. Thank you very much! Pleas keep making such high quality content.
2:51 Needs a correction. The asteroid impactor that hit the Yucatan peninsula was not 80km, but more around 10km. 80km would have absolutely demolished that entire face of the earth.
yup, saying 80km instead of 10km might not feel like a huge difference but the asteroid mass is actually 512 times more since its about volume, so a 80km asteroid would amount to 512 dinosaur extinction asteroids.
This is fascinating in how all life on Earth has adapted in some way to survive in the otherwise toxic atmosphere. Indeed, many lifeforms are downright reliant on it. This carries with it the implication that potential alien lifeforms that would have evolved in vastly different ways may find our atmosphere to still be extremely toxic to them.
i once read a joke story about how aliens don´t want to contact us because we breathe/drink Rocket fuel and shurg oxidation of as something completly normal
@DESI EDM BEATS yeah i mean humanity is kindof scary if you think about it. One moment we bash our heads in with our neighbor and if a biggger group approaches we stand next to same guy we just punched a moment before. We had to make a study if using a nuke would self immolate our Atmosphere because we realy wanted to use a nuke. We threaten ourself with mutial assured destruction. We have more working ideas on how destroy our biosphere then how to save it. We depend on a chemical compound of Natrium and Chloride. In terms of Stamina we can basicaly outpace anything if the person in question is modrratly fit (as in we wont catch a deer in a sprint but the deer will lose a marathon) Humanity is hella scary and irrational if you think about it in a neutral way. Makes it fun though beeing one of those scary apes! Also we are curious af i mean wich african animal would see the arctic circles and think "imma cross tha mf of an ice desert" or who intheir right mind would think sitting atop a selfsustained semi controled permanent explosion is a good idea because you realy want to touch the white stone thingy in the night sky
It also shows life will find a way after us. As long as we're not able to create climate control for our own, but instead destroy everything while polluting the atmosphere with CO2 that's going to suffocate is, other life forms will take our place. And maybe might take a few hundred million years, life will restore itself in ways we can't even imagine.
eaten by their lover soon as done mating... (plants give off toxic oxygen 'waste' from their point of view) Nature is strange.. cherry picking and taking things out of context in the name of science is shameful.
@@Laserblade I'd say its a stronger reflection on your lack of personality. Also I am not easily entertained, your dad had to push back and moan for me to finish.
What a great channel! I can remember that once National Geographic and Discovery Channel had beautiful documentaries but these days are gone so I am very glad to stumble upon your channel very recently. Please keep on the good work!
The place that needs more thought is: where and how did photosynthetic bacteria survive the 400-million years of Snowball Earth with its mile-thick ice sheets everywhere? On volcanic cones?
Brilliant and haunting. The antiquity of life on Earth is mind-boggling and strangely familiar at the same time. We stand on the shoulders of microbes.
I enjoyed it too. Watched it from my hospital bed in Cardiff Cancer Unit, only just saw it but thoroughly enjoyed it. 60 yrs old in a couple of weeks time. Greetings, UK.
There's always so much information available on the internet nowadays. Some people even find it over whelming. We aren't exactly use to this as a species but I'm sure we will catch up. As for extinction, it could easily happen to us. It's happened several times before.
I took a couple of college geology courses in the early 1970's, and the oxygen catastrophe was not mentioned. Therefore I assume this is newer science. The hot controversial topic of that time was a radical theory called "Plate Tectonics" - a process we humans experience many times per year on this planet.
Few people realise just how recently the theory of Plate Tectonics became accepted! I thought this was obvious stuff that would have been worked out by those wealthy gentlemen scientist explorers of the 19th or 18th century. Then I stumbled across the story about how arduous the journey to get the theory accepted actually was, & that it took so long. It was in a lovely coffee-table book by Bill Bryson entitled "A Brief History of Everything" that I found in a Thrift Store for a few bucks, as it was already 10 years out of date... To think we'd already put men on the moon more than once & the scientific/geological communities were still giving its main proponent an incredibly hard time to the point of ridicule!😳
i wasnt too far behind you and learned about geosynclines, miogeosynclines, eugeosynclines and all that rubbish. but we did learn about tectonics as well. it was new, i guess i got the cross over time. I did learn about the oxygen event, snowball earth and all that.
When I was in elementary school I remember thinking that Africa and South America fit together like puzzle pieces. All the teachers said we were wrong! Science gets replaced by better science!
I was just recommended this channel. This is just what I have been hoping for: A more detailed history of earth's geology and biology. In fact, once this series is over, I would be happy to see more episodes about early chemistry, thus binding the physics, geology and biology. Altogether, this is excellent viewing!
The craziest part to me is the timescale of it all, the original oxygen producing microbes were caught in a cycle of near extinction and rebirth for *millions* of years. That's an incomprehensible amount of time to us. The dinosaurs clung onto life for 30k years, which is like half of the amount of time we've been around as humans. Their extinction event lasted for half of our history. I just imagine if something similar happened to humans, we act like we'd be wiped out in a flash but maybe we'd still stick around for a long, long time slowly dying off. There was so much time, and so much evolution, in order to lead to us as we are today. And someday we might become extinct, but life will go on and the world will be entirely reformed for new kinds of life to an unrecognizable degree.
@@florianpeter7045 We do actually. It takes a surprising amount of it in the air to become toxic, especially if there is still enough oxygen present. If that were not the case, we would not survive submarines.
@@izzyplusplusplus1004 Not really. They don't produce large amounts of oxygen and it diffuses away pretty quickly. The dose, as we know, makes the poison. It's a problem when you get exponential growth but those are extraordinary circumstances.
Best science video I have watched. Excellent intro to the O2 catastrophe with brief overview of the lesser but great K-Pg extinction and the Permian-Triassic Extinction. Thank you to the producers.

Makes you wonder how many frozen planets are out there, having the same problems we had, except not grtting out of the freeze, heat, or other accidentally introduced change on the path of evolution. Trapped somewhere under layers of ice
But then it probably wouldn’t have looked like our early earth, highly geologically active with magma everywhere and a very active core. Earth was never destined to stay a ball of ice forever, inevitably the great volcanic activity within would’ve always broken it apart, like it happened
I love this channel. I never realized I was so interested in geology. This channel, covers in detail, all aspects, of what we know, about our earths formation. I'm always waiting for a new vid!!!!
So I don't think there's any evidence on how long after the asteroid impact the non-avian dinosaurs survived. 30K years? Or 30? Or 3? Or were they all wiped out when the Earth became an oven at 800 degrees, during the first 24 hours after the impact. Since there are almost no fossils for the first 10K years after the impact, it's pure speculation. Also, as has been mentioned, avian dinosaurs were nearly indistinguishable from modern birds before the impact. There were many types (species) of avian dinosaurs, with fundamental differences but all pretty much looking the same, of which only one species survived the impact. Birds really are an entire Class of animal descended from that single species of dinosaur that made it thru. The same goes for mammals. Every mammal alive today is descended from the very few species of mammal that made it through.
@@jamesa901 yeh I was going to say, non-avian dinosaur fossils have only been found below the KPg boundary and even then not touching the boundary, and to take it further any dates are just dates of specific eatable rock, not the fossils, saying the extinction took x amount of time just seems like a flawed statement.
I wonder if this is the Great Filter - emerging microbial communities will almost always end up changing their environment and wiping themselves out. Maybe Earth was very, very lucky that anything survived.
I doubt it. 1) Every star radiates more and more heat as it ages. So oxygenation and global ice age are needed to escape runaway greenhouse effect, like what happened on Venus. 2) This happens slowly enough that some life will survive somewhere until the planet warms, thanks to geological activity and the star heating more and more. After all, frost does not kill most simple life forms. They just have to wait. So, I think it's rather the opposite : IF photosynthetic life does not appear soon enough on a planet, THEN volcanic activity and increased solar radiation send the greenhouse effect into overdrive. And while it's possible to exit an ice age, it's impossible to exit a runaway greenhouse effect : the ocean boils away, CO2 accumulate in the atmosphere and you end up with a venusian world, where life is mostly impossible.
@no no The Universe has a number of stars that we would consider vast, but we don't know how many planets are needed for it to be more likely than not that at least one of them has a technological civilization at least advanced as ours. It may be that the number of planets needed to make a technological civilization more likely than not is so large that it makes even the number of planets in the observable universe seem small in comparison.
@no no So what if the chances of one of those planets getting life is 1 in 100,000,000,000,000,000,000,000,000? We should expect the universe to be completely lifeless, then, making us improbable.
@no no "Sheer numbers alone make other life a statistical probability." If, statistically, the chances of life emerging on a planet are 1 in 100,000,000,000,000,000,000,000,000 then statistically we shouldn't expect any life in the observable universe at all, making us a rarity.
I never learned anything about how this extinction occurred from my sicence classes until just now. This is a wonderful series that hopefully is being taught in schools today
I know what you mean. A scientific theory says that if one gets caught in an event horizon of a black hole we can see the beginning & the end. I call it the 4th dimension but its a conversation that can only take place between 2 highly gifted intelligent people. My problem is I am surrounded by fools.
The deepest meaning of change imaginable, the creation of an oxygen atmosphere changed everything. There is a record written, and it is in stone. Iron oxide bands.
I'm so glad I found this channel. I'm a geochemist doing my master's and so often we work on rocks and stromatolites from the GOE. It's so awesome finding a youtube channel covering it. Too often I find my work very fringe...and a bit sad when no one else chats about it.
How soon after the late heavy bombardment did the cyanobacteria in stromatolites appear? Do you really think that was long enough for such complexity to evolve? Could today's observed mechanism of evolution, destructive mutations, _ever_ have produced the complex machinery of photosynthesis?
Wow you are very talented! It was clear and beautifully presented without any of the usually anomalous clips that are used by other creators to bulk up their videos.

Thank you so much. I have two degrees in "experimental" paleontology and can always benefit from learning more. The careful voice, well-written text, and appropriate, pleasing video content make these all work so well.
_"Paleontology"!_ Then you've examined the layers up close and in person. Doesn't is seem odd that processes "now in operation" switched so immediately and completely between depositing sandstone, shale and limestone for millions of years each? And that there's little evidence of contemporary erosion between and among the layers that must have been exposed for long periods during deposition?
Amazing video, powerful narration. I don't think I have ever watched a documentary that is 27 minutes long, but I watched the whole thing without any skips.

True, Charlene. I just found this video by accident, wanting a brief respite from the toxic noise of the modern world. It's ironic considering that the subject matter of the history lesson was of the great chemical violence of the ancient world. Oh well, at least it's not humans yelling at each other. : )
Nothing's been right since humans took over the planet. But you need not worry, the earth will repair itself after we're gone. Hopefully "intelligent" beings will never evolve on this planet again. Nature expirmented with "intelligence" and it failed.
Deep time never ceases to fill me with an awesome sense of deep existential dread. I had a good friend pass the other day, and I wonder where his conciousness is right now. Really baffles me.
Time is a mind boggling concept, isn't it? So much of it has passed and there's so much more to come; and we're here, alive, for just an instant(relatively).
To me it's quite the opposite: It reminds me of a quote attributed to Mark Twain: "I do not fear death. I had been dead for billions and billions of years before I was born, and had not suffered the slightest inconvenience from it."
I'm only 3 minutes in and I'm so utterly hooked to this video. I've seen quite a lot of your documentaries -most are great, but this one is SO GOOD. One hell of an intro
Do you have a link for that? Ageing is also something our genes allow to happen: if they would put more effort in preventing ageing, it would reduce their spread through other individuals.
@Peter T: "Do you have a link".... A modern expression for lazyness? Genetics is A factor in aging. Oxygen is A factor in aging. UV Light is A factor in aging. There are multiple factors that cause, or play a role of some sort, in the proces of aging, not limited to the three factors as mentioned above: there are more. These factors exist simultaneous, and are not mutual excluding. This is common knowledge, to be found after a 5 seconde search on the internet. You should try it! Tip: Google search is a quite handy tool to find information yourself.
@@e.f.vangelder6810 - I asked for a link because: 1. I doubt that oxygen would be still considered TOXIC for human tissue, after we have adapted for billion of years, but I'm no expert: does scientific consensus among biologists call it toxic? 2. How large would the contribution of oxygen to aging be, compared to others, like radiation damage (I thought more of radioactivity than UV that damages only outer layers, doesn't it?), chemical damage from nitrates and others, etc. etc. 3. My guess is that our genetic programming dominates how old we can become and that the 20% O2 in the atmosphere are just the background that our genetic program uses to adjust our maximum age. "Blaming" oxygen for our aging would be misdirected.

Amazing! The fact that life has persisted on earth through so much and has existed in so many different ways gives me hope that phenomena like it are happening everywhere in the universe!
Superb quality of education. I have never benefited from such a beautiful presentation of elaborate specific information in such simple yet complete terms. . Thank you
What a great presentation. I knew about oxygen killing off the original microbes but not the extent of what followed. The idea that oxygen almost killed the entire planet is hard to grasp, but your explanation of the chemistry makes it understandable not to mention fascinating. Now, subscribe and find another one of your videos. Thanks so much for posting this.
Not really. The microbes lived in the sea and the sea is water and water is H2O. At some point that molecule had to be formed and to do that the oxygen had to be available. I would like to hear the explanation of the original creation of water and the supposed absence of oxygen in the atmosphere.
@@davidtuer5825 Actually Oxygen is a higly reactive element interacting with most common elements found in a planet and so it is very abundant in the Earth's crust. But because it is reactive, free oxygen is almost impossible to find in a planet's atmosphere without artificial interference by life. If we would find free oxygen on another planet, chances are that is because of life.
British science show use a more common parlance (not complaining). Like instead of saying "near total die off" they use the word like "decimated" (twice here) which in its proper use means "killing one tenth"
Thanks! I was wondering if I was the only one who caught that. Pretty sure an 80 km asteroid would have taken us back to zero, as far as planetary life goes.
Excellent production and exactly the kind of educational material that should exist on TH-cam. Here's something to consider. It took an asteroid strike to wipe out the dinosaurs, but if that hadn't happened, perhaps we would not have existed and today, giant beasts would roam the earth, unable to create technology. I wonder how many planets are out there that are filled with complex alien life, yet they never advanced enough to be able to master technology and therefore, not be able to send signals across the cosmos.
I’ve never heard the theory there was something the predated the Cyanobacteria that produced oxygen. The fact it utilized infrared light is also intriguing. It does make sense though. Producing sulfur would allow the microbes to spread out from the sulfur vents, which would help to ensure when new variants, those producing potentially toxic metabolic biproducts, wouldn’t just kill off all the previous generations, allowing for greater genetic diversity.
When the video started I was afraid you opted to go for the cheap popular option of skipping a few billion years and going straight to dinosaurs. Luckily, it turned out we went back to where we were chronologically. I love this story of earth as it progresses step by step through time.

This video details why, probably, we haven't met any aliens. Not only are we lucky to be here after the oxidation event, but the great dying as well. However, rather unintuitively, we might be lucky to be here BECAUSE of the meteor that took out the dinosaurs. This universe is so savage.

John McNulty. Even anaerobic bacteria with metabolic pathways , with the ability to self replicate asexual still is making it a very complex process, not by accident. If asexuality was first, then how did a male/female procreation, come up into existence separately first on their own by accident? And then somehow meet up together after having come into existence separately by accident with the right biological micro machinery? Ignorance is at play here in people not knowing any better making them an easy target for misinformation in the assembling of atoms and amino acids at the molecular levels. Having the right machinery with matching parts, in order to exchange the correct genetic information or coding , by accident is a problem insurmountable by biology alone? This is a very, very, very , very complex process. How was all of this, by ACCIDENT? It wasn't. === Evolution = Self Assembling Atoms Impossible =====

@@Pfhorrest Its not though. It's not comparable. Humans are not effecting climate to the level of causing extinction events or ice ages. The earth goes through cycles mostly driven by our own star. Our magnetosphere is weakening more than ever and all it takes is the right CME to create another Carrington Event. No electricity for some years after that.

@FRANKLIN WILSON So what have you got......not much I'm betting
Except it still talks about evolution as a proven theory. Evolution is an antique science.
It is mesmerising! It gives my scrambled brain cells something to focus on.
I’m thinking of it as a history lesson everyone needs to watch, because now we are the microbes!
It started from microbes, but how did these microbes come into being ?
It's interesting to note how amazing and powerful photosynthesis seems. Like when we think of plants (or algae, etc.) it's almost magical, because they generate energy and grow without needing to harm other organisms (directly anyway). So it makes sense that when this process first started evolutionarily, it was extremely unstable and TOO powerful and sort of got into some cascade effects.
Plants may make simple sugar through photosynthesis, but make no mistake, plants need dead things to get the nutrients to grow. You can't put a plant in sterile soil and think it's not going to die. Not to mention, there's around 750 different species of carnivorous plants alone, nevermind the thousands of parasitic plants like strangler figs that directly harm other organisms as part of their life cycles. Life feeds on life.
Perhaps we can remake it powerful quite a bit to take more co2?
I suppose it depends on how you view power. It's pretty amazing but considering how long photosynthesis has been around you would think plants would develop better ways to avoid being eaten. Perhaps that in itself shows the limitation of what plants can do really, they can make their own food but not defend it, at least not from other creatures which can move and consume.
@@Anotherguy1st “Defense” is the product of a scarcity that plants don’t really deal with. Because they get their energy from the sun, plants don’t need to defend themselves; they make more of themselves faster than any animal could ever eat them, and most plant species don’t really come into conflict with other plants. Not to mention that in many cases, being eaten by animals is to the plants’ benefit.
You can bet that if it were efficient, plants would defend themselves more actively, but often they just resort to passive measures like thorns and needles. What does it say about power that it’s more efficient for plants to make more plants? That no matter how many die, there will always be more, like cutting off the heads of a hydra?
@@Anotherguy1st Plant do have defense mechanism even against animal. They release toxin when they detect they are eaten, to reduce digestability, mess with the herbivore metabolism, or straight up poison him, a shit load of psychoactive substances like caffeine or nicotine are actually insecticide produced by plants. And there is also torn and spine, those are defenses too despite being passive.
It’s amazing what humans have been able to learn and accomplish in a very short period of time. I’m always blown away by the fact that the earth has lived billions of different “lives”.
Hardly billions, maybe dozens.

@@sandiboots123 In the neighborhood of 4000ppm in the Cambrian ca 500 Ma. to a low of 180ppm Quaternary glaciation (which by the way caused a considerable die-off) which is nearing the cessation point for photosynthesis and O2 generation. Of course the IPCC won't tell you that as they push for that level. They also don't tell you what happened during the Eocene.....life bloomed, new species (especially hardwoods), etc etc., very warm and high CO2 levels far more than today.
The big difference is the time it took for big changes during these mass extinctions.
Now we have concrete pouring across all areas, all forests and high diversity zones being choped and hunted down. Yes carbon levels may have been higher many years ago, but we are destroying the basic chains for any ecosystem to survive with no time to adapt.

I just love this stuff, even billions of years ago success breeds demise
Not only that, demise itself was the foundation for future successes.
We search for complex alien life but life itself is an unending chain of failed attempts and fateful recoveries. What are the chances for a similar outcome? While greater than zero, I'd say it's incredibly improbable.
The Universe is not teeming with life in spite of fat chances for life to appear. That's simply not good enough. Life constantly needs catastrophe to recover from and also evolve further. Without any failings, life will wither away when the inevitable tragedy will come.
Thus, the meek will once again inherit the world, unless even they are too proud facing their doom.
Demise? Decimation? Destruction? 'I don't think so, Tim'...Success breeds more success. Selecting out any life that is unable to adapt quickly enough. Is that what you mean?

We survive because the earth was terraformed but if we keep convincing ourselves that using the abundance of food an energy from that is wrong to do so, we will expire ourselves and from that, birds would probably rise. Chemistry has a few likely outcomes and things keep evolving in relatively predictable directions, especially where a medium like water, Co2, nitrogen, sulfur, heat etc are concerned.

There are a few mistakes in the video. For instance, the K/T extinction impactor had a diameter of about 10km.
2:51 Needs a correction. The asteroid impactor that hit the Yucatan peninsula was not 80km, but more around 10km. 80km would have absolutely demolished that entire face of the earth.
yup, saying 80km instead of 10km might not feel like a huge difference but the asteroid mass is actually 512 times more since its about volume, so a 80km asteroid would amount to 512 dinosaur extinction asteroids.

This is fascinating in how all life on Earth has adapted in some way to survive in the otherwise toxic atmosphere. Indeed, many lifeforms are downright reliant on it.
This carries with it the implication that potential alien lifeforms that would have evolved in vastly different ways may find our atmosphere to still be extremely toxic to them.

There's always so much information available on the internet nowadays. Some people even find it over whelming. We aren't exactly use to this as a species but I'm sure we will catch up.
As for extinction, it could easily happen to us. It's happened several times before.
I took a couple of college geology courses in the early 1970's, and the oxygen catastrophe was not mentioned. Therefore I assume this is newer science.
The hot controversial topic of that time was a radical theory called "Plate Tectonics" - a process we humans experience many times per year on this planet.
Few people realise just how recently the theory of Plate Tectonics became accepted! I thought this was obvious stuff that would have been worked out by those wealthy gentlemen scientist explorers of the 19th or 18th century.
Then I stumbled across the story about how arduous the journey to get the theory accepted actually was, & that it took so long. It was in a lovely coffee-table book by Bill Bryson entitled "A Brief History of Everything" that I found in a Thrift Store for a few bucks, as it was already 10 years out of date... To
think we'd already put men on the moon more than once & the scientific/geological communities were still giving its main proponent an incredibly hard time to the point of ridicule!😳
i wasnt too far behind you and learned about geosynclines, miogeosynclines, eugeosynclines and all that rubbish. but we did learn about tectonics as well. it was new, i guess i got the cross over time. I did learn about the oxygen event, snowball earth and all that.
When I was in elementary school I remember thinking that Africa and South America fit together like puzzle pieces. All the teachers said we were wrong! Science gets replaced by better science!
We learn plate tectonics in high school now

I was just recommended this channel. This is just what I have been hoping for: A more detailed history of earth's geology and biology. In fact, once this series is over, I would be happy to see more episodes about early chemistry, thus binding the physics, geology and biology. Altogether, this is excellent viewing!
The craziest part to me is the timescale of it all, the original oxygen producing microbes were caught in a cycle of near extinction and rebirth for *millions* of years. That's an incomprehensible amount of time to us. The dinosaurs clung onto life for 30k years, which is like half of the amount of time we've been around as humans. Their extinction event lasted for half of our history. I just imagine if something similar happened to humans, we act like we'd be wiped out in a flash but maybe we'd still stick around for a long, long time slowly dying off.
There was so much time, and so much evolution, in order to lead to us as we are today. And someday we might become extinct, but life will go on and the world will be entirely reformed for new kinds of life to an unrecognizable degree.

@@izzyplusplusplus1004 Not really. They don't produce large amounts of oxygen and it diffuses away pretty quickly. The dose, as we know, makes the poison. It's a problem when you get exponential growth but those are extraordinary circumstances.

Marvelous! A big thank you to our host. Learned a lot. Life is precious.
Makes you wonder how many frozen planets are out there, having the same problems we had, except not grtting out of the freeze, heat, or other accidentally introduced change on the path of evolution.
Trapped somewhere under layers of ice
Judging by the lack of any sign of other intelligent life in our huge universe - probably quite a few.
But then it probably wouldn’t have looked like our early earth, highly geologically active with magma everywhere and a very active core. Earth was never destined to stay a ball of ice forever, inevitably the great volcanic activity within would’ve always broken it apart, like it happened
Actually it’s Carbon Monoxide planets not frozen.
There's a couple of Moons like that in our Solar system, Europa may be in a similar stage ..
don't be delusional, we don't even know that there are other similar sized "planets" out there

3:09 The extinction of the dinosaurs took "...a mere thirty thousand years..." Let's just stop and think about that on a Human scale shall we?
Its crazy, we're BY FAR closer in terms of time to the T Rex than they were to the earliest dinosaurs.
So I don't think there's any evidence on how long after the asteroid impact the non-avian dinosaurs survived. 30K years? Or 30? Or 3? Or were they all wiped out when the Earth became an oven at 800 degrees, during the first 24 hours after the impact. Since there are almost no fossils for the first 10K years after the impact, it's pure speculation.
Also, as has been mentioned, avian dinosaurs were nearly indistinguishable from modern birds before the impact. There were many types (species) of avian dinosaurs, with fundamental differences but all pretty much looking the same, of which only one species survived the impact. Birds really are an entire Class of animal descended from that single species of dinosaur that made it thru. The same goes for mammals. Every mammal alive today is descended from the very few species of mammal that made it through.
@@jamesa901 yeh I was going to say, non-avian dinosaur fossils have only been found below the KPg boundary and even then not touching the boundary, and to take it further any dates are just dates of specific eatable rock, not the fossils, saying the extinction took x amount of time just seems like a flawed statement.
They burrowed deep underground in the cool, moist soil.
This is the best thing I have seen on TH-cam. Simply wonderful. You have imparted the poetry of science. gorgeously clear Musically spoken
I wonder if this is the Great Filter - emerging microbial communities will almost always end up changing their environment and wiping themselves out. Maybe Earth was very, very lucky that anything survived.
I doubt it.
1) Every star radiates more and more heat as it ages. So oxygenation and global ice age are needed to escape runaway greenhouse effect, like what happened on Venus.
2) This happens slowly enough that some life will survive somewhere until the planet warms, thanks to geological activity and the star heating more and more. After all, frost does not kill most simple life forms. They just have to wait.
So, I think it's rather the opposite : IF photosynthetic life does not appear soon enough on a planet, THEN volcanic activity and increased solar radiation send the greenhouse effect into overdrive. And while it's possible to exit an ice age, it's impossible to exit a runaway greenhouse effect : the ocean boils away, CO2 accumulate in the atmosphere and you end up with a venusian world, where life is mostly impossible.
@no no The Universe has a number of stars that we would consider vast, but we don't know how many planets are needed for it to be more likely than not that at least one of them has a technological civilization at least advanced as ours. It may be that the number of planets needed to make a technological civilization more likely than not is so large that it makes even the number of planets in the observable universe seem small in comparison.
@no no So what if the chances of one of those planets getting life is 1 in 100,000,000,000,000,000,000,000,000? We should expect the universe to be completely lifeless, then, making us improbable.
@no no "Sheer numbers alone make other life a statistical probability."
If, statistically, the chances of life emerging on a planet are 1 in 100,000,000,000,000,000,000,000,000 then statistically we shouldn't expect any life in the observable universe at all, making us a rarity.
Considering their fast rates of evolution, it is very unlikely for the while biosphere of microbes to wipe itself out

Oxygen is still toxic even to organisms that need it to live: this toxicity is a major cause of senescence (ageing) in vertebrates.
Do you have a link for that?
Ageing is also something our genes allow to happen: if they would put more effort in preventing ageing, it would reduce their spread through other individuals.
@Peter T: "Do you have a link".... A modern expression for lazyness?
Genetics is A factor in aging. Oxygen is A factor in aging. UV Light is A factor in aging.
There are multiple factors that cause, or play a role of some sort, in the proces of aging, not limited to the three factors as mentioned above: there are more.
These factors exist simultaneous, and are not mutual excluding.

2. How large would the contribution of oxygen to aging be, compared to others, like radiation damage (I thought more of radioactivity than UV that damages only outer layers, doesn't it?), chemical damage from nitrates and others, etc. etc.
3. My guess is that our genetic programming dominates how old we can become and that the 20% O2 in the atmosphere are just the background that our genetic program uses to adjust our maximum age. "Blaming" oxygen for our aging would be misdirected.

Not really. The microbes lived in the sea and the sea is water and water is H2O. At some point that molecule had to be formed and to do that the oxygen had to be available. I would like to hear the explanation of the original creation of water and the supposed absence of oxygen in the atmosphere.

Excellent production and exactly the kind of educational material that should exist on TH-cam.
Here's something to consider. It took an asteroid strike to wipe out the dinosaurs, but if that hadn't happened, perhaps we would not have existed and today, giant beasts would roam the earth, unable to create technology. I wonder how many planets are out there that are filled with complex alien life, yet they never advanced enough to be able to master technology and therefore, not be able to send signals across the cosmos.
I’ve never heard the theory there was something the predated the Cyanobacteria that produced oxygen. The fact it utilized infrared light is also intriguing. It does make sense though. Producing sulfur would allow the microbes to spread out from the sulfur vents, which would help to ensure when new variants, those producing potentially toxic metabolic biproducts, wouldn’t just kill off all the previous generations, allowing for greater genetic diversity.
When the video started I was afraid you opted to go for the cheap popular option of skipping a few billion years and going straight to dinosaurs. Luckily, it turned out we went back to where we were chronologically. I love this story of earth as it progresses step by step through time.
