    • 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.

  • 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.

    @GraemePayne1967Marine@GraemePayne1967Marine10 ай бұрын
    • 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entitled "A Brief History of Everything" that I found in a Thrift Store for a few bucks, as it was already 10 years out of date...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!😳

    • 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.

  • 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.

    @alexanderplatypus3664@alexanderplatypus36642 жыл бұрын
    • 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.

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?

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.

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.

    • 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.

  • 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! :)
