too Greatttttttt, I was so deeply inside, I expect part 6 and .... more... to enter the Dinasaurs age and later on til this modern life, but unfortunately it was the end.
@xOxKurdParstxOx well, I have all sort of Scientific documtary here, you may want to wacht my other documentary video (Earth Story by Prof. Aubry Manning), its one you never forget, I have the entire series here for you to enjoy...Thanx
If you look at Walking With Dinosaurs, the half-mammal-half-reptile creature appears with the Coelophysis, but is endangered by 30 million years after the Permian extinction; nevertheless, it produced mammals that, eventually, produced us. We're one lucky class, mammals.
Very interesting programme. Thanks. It's sad that all that life died. but then again, if it hadn't modern life, including our own species, humans, might never have evolved.
@benthejrporter you welcome...very true the demise of those species let to our own one to evolve and take over, but then the Dinosaurs for example were around for almost 165 Million years, we human only 3 millions and for how long we think we can stay put?
@KurdstanPlanetarium I don't know. It depends on how long the Earth's habitat is favourable to our species. Sadly we're undermining that habitat ourselves, so unless we change our ways we won't be around much longer. If we go down we'll also take many other species with us, infact we already have like the Dodo and Chinese River Dolphin.
@benthejrporter its true human desires and greed have no limit and speeing up disasters but the way of nature is more powerful, no matter how much we try to do on human level, Nature surprises us once more by whatever she thinks best to deal with us, a stray asteroid or a comet no doubt about them, or continental drifts once more bring about one gaint land mass Pangea and a sure death to our and many other species, the only solution for us is out there in Space colonies I belive!!
@KurdstanPlanetarium In the end we'll get out into space I'm sure. There are many wonderous things in the world and it's best not to get too attached to them because we and everything else seem to be transient, like one of those Buddhist sand pictures. (BTW, why have our conversation posts had so many negative votes?)
I don't know if it is true, but I read somewhere that Listrosaurus populated around.... (what was it)... 90% of all life on land after the Permian extinction! That's huge!
@Warhiji Based on what I've read, Lystrosaurus was the most numerous single close range of species ever known. The delay in the evolution of effective large predators (who, after all, can't exist until large prey is around) after the Permian extinction let them grow to huge numbers. Perhaps as much of 95% of land vertebrates were this species at one time.
An interesting documentary, but for a mass extinction that was concluded, within the documentary itself, to have occurred in three phases over the course of an 80,000 year period, can you really help but not find the title the people at the BBC chose to give it: “The DAY the Earth Nearly Died” (keyword: DAY) to be a little misleading and exaggerated?
Not trying to suggest anything bad about the BBC, just saying though…
@silentf0e yes I see what you mean, What a Day that lasted for 80000 years...well to me its an expression, thought as you said not literally correct one, but we have to take it for the time period, that supposed to have lasted that long...just for the record "the longest day in our solar System belongs to the Planet Mercury that lasts 177 Earth Days, that is twice the length of the Mercurian years"..
Thanx for pointing it out, wonderful comments...well done
Hi ...what exactly in the name of the creature in the min 8:42 at the end of this P5 I was reading the comment from N00bcrunch3r .. about it !!! Looking for more info concerning about this notation I founded differents source but not really in connection with the creature in the min 8:42 of P5
@ChannelingusIV yes thats true, every giant impact is necessary for Earth to split apart in the anti pod of the impacting body...so that 300 mile crater is the scar of a giant impact, its shock waves created the spliting of Siberia and the subsequent spliting the land there, which resulted in releasing curtains of lave for tens of thousands of years and as a result the Earth temperature rose which casue the great dying of the Permian Era..
I smell a huge flaw at the end! Listrosaurus was a Dicynodont. Dicynodonts are only distantly related to the ancestors of mammals. The real ancestor of mammals at that time was cynognathus, a cynodont.
I was speaking of the early Triassic, which both Listrosaurus and Cynognathus lived in. At the end of the Permian period, our ancestor was Procyonosuchus.
Were there not other periods, too, when earth climate rose to similar temperatures, but without 95% extinction?
Whenever I hear global warming nowadays I become especially sceptic. Its way too much a fashion thing. Just like all the popular impact theories. Theyre just sexy, people love em because its so violent and catastrophic.
I mean, its quite entertaining to ponder all these theories. But its stupid to take them all to seriously.
@Skandalos oh sorry you got it all wrong...risng temperature 10 degrees does not sound too much, specially you can achieve that in your room teperature.but to earth that has average temperature of 15 C degree, it mean dying out many speciese of life.
just imagine curtains of volcanic lava erupts for tens of thousands of years, what impact has that on our eco system...just remember Sahara used to be an oasis b4 but now the biggest desert on Earth, just by global worming in the past.!!!!!
@KurdstanPlanetarium How can a sceptic ever be wrong ^^. We are told that by the siberian trapps the temperature rose about 5 degrees in the worst case, then after the oceans had warmed up, too, climate rose another 5 degrees due to greenhouse effect caused by methan rising from the ocean shore.
Earth temperatures have never been very stable, there have been lots of other warm periods. If the methan rise is triggered so easily, how come there were no other similar extinction events?
@Skandalos well you are rigth that Earth temperature have never been stable..but do you know how many extinction peroids have past on Earth more than could be count...but this one is called the mother of all extinctions, or sometimes called the Great Dying
I try to send you one video about that...its too long about 45 mins long if you have erge to watch it..very interestng
@Skandalos I'm pretty sure it wasn't just the heat and the methane. I've heard that the C12 stagnated the atmosphere by removing large amounts of O2 from the air, thus suffocating animals too large to efficiently use what was left.
You're right though, we shouldn't treat science as a sort of pseudo-religion to be followed without opposition. That's against what science is about in the first place.
So there was no meteor impact? In the summation near the end, it implies everything started with the Siberian Traps. What started the Traps? I've seen other videos where it was actually the meteor impact in Antarctica that started the Siberian Traps in Russia because of waves through the Earth that cracked the crust in that location. That got the ball rolling. Is that incorrect? I'm curious! Love this stuff.
@eepruls you are absolutely right that is my belives too, though you have seen one of the scientist went to Antractica and found out evidence of huge impact...the same happened 65 million years ago, when a huge meteorite hit Mexico the shock wave created masssive volcanice eruptions the sort of Siberian traps in the anti pod of Mixico in India, you can watch that in my other video (Earth Story) by professor A.Manning, its a great scientific documentary about Earth history...
@KurdstanPlanetarium Cool. That makes a lot of sense. It's strange that they talk about the meteor impact in Antarctica (and the evidence that it actually happened) and then don't discuss it in the summation near the end. Yes, the Antarctic impact was not large enough to cause the mass extinction alone (and would have been too rapid) but the impact itself is what started the whole process with the Traps, methane hydrate, etc. We're lucky anything survived at all!
@eepruls They were making the point that there is insufficient evidence to suggest and impact caused the extinction. As far as I know, impact induced volcanism at an antipode is not a widely accepted theory and I can't think of any other examples where it may have occurred. In any case, the video deliberately points out the lack of evidence for such a large impact to have occurred.
@KurdstanPlanetarium The Wilkes crater isn't a proven impact crater and the date it was formed is still unknown. There's also a relative lack of impact ejecta that would be expected from a crater of that size...there's quite a few holes in pretty much all of the theories, I'm personally not sure if we'll ever get a truly great explanation for what happened.
@ec688 best theories when supported by data analysis gathered from around the world are worth accepting it...as for crater ejecta, you can see them on the Moon or Mercury since they are airless and lifeless worlds...Earth on the other hand is a dynaic planet with weather, volcannos, and tectonice plates movements always reshaping Earth, so very few crates survived and definitely no crater ejecta could.
today this is our best theory thats supported by all evidences and data analysis.
@KurdstanPlanetarium But the problem is, the best theories are not accepting an impact event as the primary cause for the P-T extinction. The whole shifting and reshaping of the earth does tend to eliminate craters but not ejecta. An ejecta blanket covering the earth with siderophilic elements and other signs of an impact does not get removed...the only places where it would be removed is on the ocean floor where subduction processes leave us without oceanic crust beyond the triassic.
