@nothuman3083 8 місяців тому
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.

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.
@joerosen5464 4 дні тому
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entitled "A Brief History of Everything" that I found in a Thrift Store for a few bucks, as it was already 10 years out of date...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!😳

@Deridus Рік тому
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.

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.
@ananthropomorphictalkinggo6641 Рік тому
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.
@kettelbe Рік тому

@Anotherguy1st Рік тому
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.
@technicolormischief-maker5683 Рік тому
@@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?

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.

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.

@mecha-sheep7674 3 роки тому
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.

@r2out 3 роки тому
I didn't get teary eyes, but I sure got an injection of awe that stayed with me for a good amount of time; the history of the earth and life is an EPIC adventure, but only for those addicted to awesomeness.

No I didn't. Intriguing but no emotional/spiritual experience here.

It gives me goosebumps whenever I try to imagine billions of years of history.

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.

This is surprising, a documentary on youtube that seems well grounded and not full of complete nonsense.

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.
@bobthabuilda1525 3 роки тому
Crazy thought, isn't it?
@oliversmith9200 3 роки тому
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.

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. Cheers! :)

When I'm ready to sleep I scroll down UKposts until I find one of your videos, then drift off while imagining ancient history.
