I admit, that my highschool chemistry is a bit rusty right now, but I think there is mistake at 7:10. When you mix SO2 and H2O result will be H2SO3 not H2SO4. H2SO3 is still acidicic, but nowhere on the level of H2SO4. If the H2SO4 was raining down on us fun would be over very soon...

[@marekptasznik1402]

There is possibility that SO2 in presence of Nitrogen oxides as catalyst might convert intoSO3 and form H2SO4. The amount and concentration of the acid might be not large enough to kill living organisms on Earth. It will however alter enviroment and inhibit some organisms in favour of more low pH tolerant forms. Just speculation.

[@stevebennett2781]

Sulfurous acid, H2SO3 becomes Sulfuric acid, H2SO4 by accepting another oxygen atom out of the atmosphere.

[@therealspeedwagon1451]

The freezing event that most interests me is the Huronian Glaciation some 2 billion years ago. This was around the Great Oxygenation Event, which occurred when oxygen produced by Cyanobacteria reached a tipping point in the atmosphere. This oxygen was a poison for all other forms of anaerobic life, so this caused one of the first mass extinction events in life’s history. This, along with a general lull in volcanic activity lead to a glaciation event that lasted for an entire 300 million years. Although it’s still debated whether this was a true Snowball Earth or just a series of intense glaciation events.

Extremophiles, those little things that live off of volcanic vents and stuff, could they have had a hand in preserving life? This was not brought up in the video.

[@sacrecharlemagne2262]

There are sponges that live by vents so it's possible they are saving that discussion for the next video.

[@Dragrath1]

The problem with suggesting hydrothermal vents as the sole or main abode for life during the cryogenian is that they do not produce the conditions for oxygenated water and evidence suggests the sea floor was probably largely anoxic before the ice developed with deep water fossils not showing up until the Ediacaran. Sponges are multicellular Eukaryotes meaning the lack of oxygen at depth is a pretty big deal. Of course we can't rule out the possibility since sea ice formation can drive the sinking of seawater the problem is that during the glaciation most of the ice deposition was occurring at the poles and as such there wouldn't be exposed seas to absorb oxygen into the water. However Sponges are quite simple compared to other animals so it makes a low oxygen environment far more likely than an active animal. There are many sides to this argument and there isn't yet a consensus on the issue. Probably the larger issue at least according to some of the papers I have read is that the Sturtian overlaps with the time period that molecular clock dating suggests for the divergence between bilaterians and cnidarians two major orders of mobile complex animals which most modern animals are descended from. Given the number of surprisingly complex traits shared by both groups the last common ancestor was likely a mix of both groups with two major body layers one of which would divide into two separate layers in bilaterians a well defined body axis muscles and a neural network. Those are energy expensive traits that likely needed an oxygen rich environment. Don't get me wrong I have no doubt that things like sponges could probably meek it out in a volcanic environment but an environment where worm like mobile organisms could evolve. For that the leading hypothesis last I checked bolstered as models continue to improve seems to be one suggesting multi cellular plant and animal life probably survived within the oxygen rich meltwater pools cracks and fissures near the equator. The issue is largely still highly up for debate so it isn't surprising they skipped this.

[@Ethan5I5]

Dragrath1 Very long, didn’t read

[@squireson]

@@Dragrath1 I was under the impression that only single celled organisms survived the very first global iceball (when oxygen ruined everything) and that the multicellular life arose (again but distinctly) after the last thawing.

[@BetaCentauri13]

If the continental plates were shifting so violently during that time period, I think their separation points would probably be where the ice was thin enough to support photosynthesis. The shifting would generate/release heat and constantly cause cracks to firm in the ice, after all.

Maybe life flourished under the thick ice by getting energy from underwater volcanoes (which some aquatic species still do on Earth, and that theory also supports that there might be life under the ice on Jupiter's moon, Europa.

What about the fact that the magnetic pole change its Direction one occasion? Could that affect the theory? And does this change the entire thesis

[@PeachesiceT]

Bill Smith Im glad someone has a intellectual thought process, I was starting to give up hope. Thanks for the wonderful words theory’ and thesis... not fact!

time traveler: do a video on how oil caused the fireball earth

[@PeachesiceT]

Felipe Lorenzzon I also thought that they must have time travel abilities. They may like to include the words theory and thesis

Technically speaking we are still in an ice age because there is still ice sheets and glaciers on earth

[@Loathomar]

@@elementus2857 Technically speaking, it is complex. The larger time period we are in, Quaternary, which is the last 2.8M years, is an ice age, but when subdivided into 2, the Pleistocene and Holocene eras, the Pleistocene was the last ice age, which ended 11,700 years ago. Though the term ice age is poorly defined as "a time of widespread glaciation", or "a geologic period during which thick ice sheets cover vast areas of land". But having an ice sheets and glaciers is not generally how an "ice age" is defined.

I can't stop watching these videos....so glad I found these!

[@lilharddad]

Could you guys do a video on the evolution of otters, i want to know how sea otters became cute and fluffy. But river otters are water goblins

[@nicholaslewis8594]

That sounds adorable and terrifying at the same time.

[@lilharddad]

@@nicholaslewis8594 exactly like otters my friend

[@melvinshine9841]

Male sea otters sometimes will essentially hold baby otters hostage so that females will gather food for them. Sea otters have a dark side, too.

[@lilharddad]

@@melvinshine9841 tbh they are all water goblins and thats ok i think

[@SlyPearTree]

The fact that life continued throughout those events and worst is very encouraging for those of us who are hopeful that scientists will find extra terrestrial life within the solar system.

I just watched one of your other videos and I have a question (if this is already a video I'm sorry): Why are so many of today's whales filter-feeders and why is this better than being able to eat larger prey?

[@jimp5133]

Design, the filter type function is part of a symbiotic relationship.

Best explanation of Snowball Earth I have ever heard. Well Done.

I wonder if the Younger Dryas cold event is too recent for Eons to do a video on.

[@PeachesiceT]

Zerontanthalas Drake 🤔 mmm curious isn’t it!

[@marin.g.studios]

That is so interesting with the carbonates! I'm working as a research assistant at uni in the geology department and I had to go through Carbonatite rocks data a month ago and now that I think of it there were so many more carbonate samples found in Canada and the states compared to other places from 500+ Ma! So interesting tying this video and the carbonatite data together wow! This made my day thanks!

[@jax1722]

You guys are the best! I love your vids. If you did something about Madagascar or New Zealand it would be so cool

[@lewisirwin5363]

They've at least covered the ratite birds (Moa, kiwi, elephant bird, etc.), so there's that one for a start.

[@jax1722]

@@lewisirwin5363 Yeah I watched that video and it was very good, I enjoyed it. But there's thousands of other strange creatures from the islands

I live in New Zealand, not entirely accurate at all!
