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?
@@daveanderson718 dude, what?
Your comment starts out very good...
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.

Lol!
Humans: We are the most disruptive species ever.
Cyanobacteria: Hold my carbon dioxide.
Humans are just getting warmed up.
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.

Comment of the year.
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.
@@KayAteCheflife will still go on with or without us. We aren’t anything special.
@@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.
Not quite billions of species, certainly more than that in numbers of individuals, but not species.
@@blucat4billions of species def existed thorough the earth’s history
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!😳
"In the beginning the Universe was created.
This has made a lot of people very angry and been widely regarded as a bad move."

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.
😂true though
Actually, I think Arthur Dent said that.
I love that quote.

"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.
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.
don't be delusional, we have no idea by looking at a piece of dirt that it's billions of years old. That's silly

This sounds so much like a made-for-TV documentary. I've seen a fair number of long-form educational videos on CZcams, and none of them made me feel like a kid watching the Discovery Channel the way this did.

As a person who likes oxygen, I don't think it was a bad thing at all.
Yet our bodies are made to function in an oxidising environment.
Strange fact, oxygen is the most carcinogenic substance on the planet..
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.
@@oo-uu9ez can't forget about the increased ignition point.
Ironic fact: Oxygen, which we need to survive, also causes us to age further than peak performance aka: decay genetically.
Getting old is a disease.
This is so well narrated that I didn’t even notice there were no subtitles, despite normally preferring them if at all possible. Masterfully crafted.
All lies though!
I'm glad we made it through that one!
I am a microbiologist and studied anaerobes and Clostrida in particular. I wrote my Ph.D thesis on the effects of oxygen on these bacteria. There is a spectrum of oxygen tolerance amongst these bacteria. They are all Eubacteria, modern microbes not Archea. I enjoyed you presentation very much.
My theory is the bacteria would spore and be taken up my evaporation, be rained on the land multiplying and oxidation of the land, released more nutrients flowing in the streams to the mouth of the oceans staining the seas red. Leaving the open and deep ocean to absorb the dead bacteria and oxygen.
My hypothesis is the seas of iron where turned to rust, removing a central nutrient from the environment wiping out most of the organisms that soaked up the oxygen or diluted it, spiking oceanic oxygen, whilst the land was turned the air oxygenated by the puddles, ponds, streams, and rivers.
Oxidation of nutrients limited the outflow, until glacier craved out sediments booming the oxygen producing life forms into dooming themselves as glaciers advanced to the poles.

We are also largely protected from comets and meteors by Jupiter.

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
At 2:50, the video states that the Chicxulub impactor was 80km wide. Consensus today puts that size at roughly 10km in diameter (e.g., about the size of Everest).
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.

The Great Dying almost wiped out all advanced life on Earth. But the Oxygen Catastrophe almost wiped out life completely, even the simplest of forms.
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.

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!
What an incredible indictment of the Discovery Channel
@@jonathanweinbaum5012 Discovery used to have good stuff. They got bought out at some point, which led to their decline, if I remember correctly.
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.
You betcha. Kind of puts a different focus on the word "pandemic".

First time of watching this channel for me and I have subsribed with great enthusiasm.
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.
This was a hell of an explanation, magnificent piece of work, bravo!
"The bacteria do not have protection against the oxygen they produce..."
This is what is technically called an oopsie.
Well we don’t have an protection against carbon dioxide, oopsie
@@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.
I find it interesting that your statement is true, and that it destroys the evolution genesis hypothesis.
@@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.

@Michael Hawaiianstyle the thumbnail did.
As a trained Geologist, I would like to compliment you on a job well done. Good explanation of a rather difficult period.
What would the peak ppm of carbon dioxide been? God this is interesting....!
my GF had one of those
@@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.
@@samconagher8495 Yup. If we go to low on the co(2), we will be done like dinner....frozen dinner.....

@@alexanderSydneyOz kind of agree
@@alexanderSydneyOz come on I can totally see that phrasing be used in a David Attenborough nature documentary or something
@@alexanderSydneyOz I thought he was talking about Vanilla Ice. Was perfect.
now though you made me totally rethink everything
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.
This is an excellent video, informative, well paced, concise, nicely voiced, with good graphics.

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.

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.
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.

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?
@@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

Definitely won my subscription. That was great, I like the way you tell the stories. Can’t wait to learn more. Thanks.
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.

Masterfully written and articulated. Very engaging, intelligible and full of references. Congrats. Keep it up!
I am in awe. This is outstanding. Thank you!
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.

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.

EXCELLENT
fantastic film. im a geologist and that was the most vivid explanation of the precambrian iron stones i have ever heard. fantastic
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.

Finally, an explanation of why the iron formations are banded.
I think the explanation has been around for sixty years but hidden in scientific articles. It's good to see it explained in laymen's terms.
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.
There are a few mistakes in the video. For instance, the K/T extinction impactor had a diameter of about 10km.
This wonderful documentary drove me to heavy tears, God~Bless You my friend.
That was very interesting to watch and listen to. Thank you for creating this.
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
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
That was a wonder filled presentation that I am thankful to y'all's evolutionary contribution. Mahalo!
I suppose in a way, one could call this prolonged event, the first great "horror story".
Indeed, listening to your fantastic narration, David, actually instilled a sense of dread in me as I listened.
It truly is a wonder that so many many times, life on this planet was almost extinguished, only for each time... "life found a way".
It makes us wonder how many other planets in the deep abyss of space, were able to either circumvent or overcome similar life extinction events. It certainly takes more than just forming in the "Goldilocks Zone" of a star's solar system, it also takes chemical-combo evolution over literal Eons to survive. No small feat!
Thanks very much once more dear Friends, I love this 'History of the Earth' storyline, as it is very well presented and significantly informative.

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?
NatGeo has decent CZcams videos.
Great video with good narration. I will watch the next one now.
Brilliant exposition. Thank you
A minority of Earthlings have been pretty damn lucky a number of times. So, let's not take any of this for granted. There exists no promissory note that guarantees or guards us fro extinction.
So true, and covid has definitely reminded us there are no guarantees in life
@@davidh6300 Respectfully, you're comparing a disease with a 99%+ survival rate to mass extinctions with a 99%+ species extinction rate. There is no comparison. None. And 400ppm CO2 isn't going to kill us all either, no matter what the "experts" say. It is events like the one in this video that ought to offer us perspective so we stop freaking out and driving ourselves into anxiety-ridden messes for no good reason.
@@kma3647 yep
@@kma3647 No. Global warming will not kill our species. But what we do now determines how severe our geoengineering will have to be.
@@kma3647 Global warming isn't about making humans go extinct; even all out nuclear war wouldn't accomplish that. The issue with global warming is the economic damage it'll wreak.

50k is no small task, however. It's enough for YT to recognize you. Besides, there are literally hundreds more covering similar topics, many in short bursts, like EONS, a PBS project, for instance. With time, it will grow as the algorithm directs viewers to the channel.

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.
It is true that one massive layer of rock is the mother of the iron age.
All rich iron ore deposits come from the era in time the great oxygenation events.
This lasted for 200 million years and occurred more than a billion yeard ago.

Hey Jenny, how often you hit the fentanyl or meth pipe?
Lesson learned: It's perfectly normal that species try to kill themselves by climatic catastrophes
And probably not believe they can have any effect on it.
Please no. We're smarter than this. We evolved brains so we could think our way out of these problems.
It's the circle of life. Innovation leads to self destruction. Maybe we should have just sticked to living in mud huts or bacteria should have stayed purple.
The lesson surely is that a balance is required. The microbes that ate the sun produced the oxygen that would eventually destroy them. To stop this happening another life-form that ate the oxygen would be needed to prevent the overload occurring. Symbiosis. 😎

Just gotta say I love the tone of voice of the narrator. Calming and soothing. Plus I learn stuff. : ) Always worth a listen/watch.
You should check out his other channel called Voices of the Past. His brother, History Time, also has a excellent tone and cadence.
In summary:
We, and all modern life, owe our existence to ancient bacteria taking the world's biggest sh*t.
Crazy thought, isn't it?
Yes, you've ingested, digested and neatly pinched off the essence of our evolution. You've baked down the substance of our beginnings into a single loaf of life. You've pegged the original instance of shit hitting the fan and opened the fecund font of bare bottomed truth in one sentence. I lack the quality of thrifty disposition, lingering on the subject and the newspaper, but, appreciate its custodians.
They literally killed themse,ves in order for us to live
Almost. First, all modern life owe their existence to long-dead stars blowing up and sending us the materials (elements) necessary to even make that petri dish (chemistry) in the ocean into life (biology) in the first place. Before that, there were only four elements in the universe. The number of what-if's and "almost extinct" are pretty incredible. It is that long duration of fairly steady conditions that made us possible, and also very likely unique in the universe, therefore valuable. You don't need more meaning than that...
They technically suffocated on their own farts. The only ones that survived turned into the modern day liberal.
Excellent program! Taking notes because this is stuff we should all know since we are so lucky to live in an age we actually can know about the planet's fascinating past.
Bravo, well done. Thank you
