Please do an episode about the evolution of grass. You've covered trees and flowers already, bit so far the only things you've said about grass was that it didn't exist in the Jurassic but started to be omnipresent (to the point where it formed a whole new type of environment) in the oligocene. Makes me really curious.
This was such a cool episode for me because I am a geologist and I did a huge term project on Lake Toba last year. I read and analyzed like 50 different scientific papers and articles supplemented with websites and synthesized a presentation to present to my professor at the end of the semester. I read the majority of papers you talked about in this video so I was "Holy crap I read that paper!" throughout most of this episode. This was such a good time. Thank you for doing this episode.

I really appreciate this episode but there are 2 comments that raised my eyebrows. The first is the reference to the malawi lake sediments. Those being relatively unaffected could actually support the idea that humans in that part of Africa world survived in larger numbers than those in Asia. At the very least that particular data point doesn't really support either the idea that Toba was or was not the cause of the bottleneck. The other was near the end when the human bottleneck is placed at 50,000 years ago, the genetic evidence is actually pointing to a date between 55-70k years ago with most of the genetic studies centering around 60k years ago but a little over 70k being at the upper end of the possible range.
One minor critique here - you mention plant communities recovering fairly quickly... but that's a bit confusing given we're talking so many different time scales here. Does this mean they would have recovered within the year, decades, hundreds of years? Can you quantify that a bit more? Quickly can mean so many different things in geologic time!
I like how in the critique you were very respectable and very nice to the person who did the video. You don’t see that a whole lot so please keep that critiquing style because it’s probably one of the more respectable ones I’ve seen
I’m not sure how fast the ‘quickly’ was but usually I would guess decades to hundreds of years, as the cycle (I forget the cycles name) starts with a disaster and after lichen and moss break down the rock into soil then different forms of plants and after generations large hardwood trees, so I’d guess decades to hundreds of years but how she worded her sentence and the types of plants she’s talking about I’d guess decades I hope that helps! But again I’m not completely sure so that what I said with a grain of salt
@@birdybathtime389 That's what I would think too, but if it didn't cause issues for humans or other animal life, then wouldn't it have had to recover quicker than that? So that wouldn't make sense. Either way, quantifying it would have been really useful.
7:58 Sulfur aerosols would indeed have a cooling effect, as they apparently did from the 1940s through ~1970, but I don’t get the argument about water vapor, unless the volcanic source significantly increased concentrations of H2O in the stratosphere, as water vapor in the troposphere has a very short recycling time, which is in equilibrium with surface temperatures. Something missing from this argument? Volcanic ash also has a cooling effect, but its lifetime in the atmosphere is quite short, as shown by the global impact of Pinatubo eruption in 1991. Some discussion of the impact on stratosphere needed.
To be fair Pinatubo(VEI-6) was much smaller than Toba, for real volcanic winter comparison it's noteworthy to look at Krakatoa (also a VEI-6, but ejected more material than Pinatubo) and Tambora (VEI-7), curiously both in Indonesia. Tambora itself was the largest eruption in the last 300 years and the largest that has been scientifically observed yet it looks weak compared to the major eruptions on Campi Flegrei and Long Valley Caldera(Also VEI-7 may i add), imagine compared with VEI-8 like Toba and Taupo.
@@caiolucas8257 Recent findings suggest that Samalas/Rinjani Tua eruption in the 13th century is even bigger than Tambora and Campanian Ignimbrite, making it quite possibly the biggest eruption ever observed.
What I love about Eons is that instead of going with the previous point of view which most programs do you present other hypotheses and opposing views.and don't tell us what to believe, just leave it up to us to decide. You also mention some viewpoints as "unlikely" or "maybe" or "probably" giving hints that some outcomes hold more water than others which helps in making that decision. Always fascinating as all Eon videos are. I have learned so much from you over the years, I can't thank you enough.
I swam in Lake Toba when I spent a week on Samosir Island (in the middle of the lake). The blast that left that size of crater behind staggers my imagination.
It's without doubt the worst natural catastrophe modern Humankind ever faced in terms of absolute size. However the Campanian Ignimbrite Eruption c. 40 Ka ago in South Italy (with rocks reaching all the way to Ukraine) was arguably a close one and for Neanderthals it was certainly the worst catastrophe ever, only a few pockets survived afterwards (but also killed many communities of Homo sapiens in the area and the end result was the expansion of a more uniform culture: Aurignacian).
@@wenderis - Not familiar except for Tambora but AFAIK it was much worse: there's been nothing like either mega-euroption ever since for all I know, these are events that only happen every so many tens of thousands of years, not in historical scale.
@@LuisAldamiz Well, it's hard enough to quantify 'explosiveness' - VEI has its limitation - defining 'worse' is even harder. The fact that eruption of Samalas, and especially Tambora, occured in historical times in a relatively populated area which affected more human (and biodiversity) should count in the 'worseness scale'.
Excellent Program as always Eon! Thank you for making it. Is there any indication of prevalent diseases in human bones prior and after the period to give us clues to overall health in global areas? I keep going back to the same idea that ice ages mean having to be in enclosed places ( caves, communal huts, and whatever else ) to survive the cold. It would be opportunity for disease to effect a population. Remember caves have bats and bats have been known to carry disease, for example. It could go through a population in a region like fire.
There are very few human remains from Asia so early. Some are known from South China but very few and rather from later dates. There's just no evidence to make such judgment, even if more fossils existed or are found in the future, chances are they'd be distant in time from the narrow period of the post-eruption.
I have this thought very often. Especially sad is story of sea cows - they lived in Bering Sea and were hunted to extinction by Europeans in 20 years...
I've always loved the story of the first giraffe in France, in a Paris zoo. Man comes and stares at it for long, long time. Turns around and says "I still don't believe it." How very human!
The explosion of krakatua in the 1890ties was seen even in Europe. Painter Edvard Munck did his paintings with assumed influence of those color changes
Another, more circumstantial point about the lack of change in stone tools from the area around the eruption is that the people there were not impacted enough to require new kinds of tools to survive. Circumstantial at best, as I am no anthropologist, but that's what I thought of
People were following specific traditions of tool-making, that's what prehistorians call a techno-culture (or just "culture" for short). Only if people survived they could transmit that tradition. We know in fact that "Nubian tradition" tools were being made in Southern India below and above the Toba ash layer. They did survive.
@@onyxgrnr666 - You have no idea. To begin with flint is a rock type, also known as silex, and not a tool type. It was the most favorite tool-making type of rock in most cases, but depends on availability. You can make axes, spears, tiny arrow points of many types, choppers, cutters, scrappers, mortar and pestle, hand mills, grinding stones for water and wind mills, catapult projectiles, tiny bladelets to be mounted in sword-like weapons, even pots and ashtrays. And I'm probably just scratching the surface of the many possibilities. But what matters here are not just tool types but tool styles: are the arrow points back-tipped or socketed for example? The diversity then becomes immense. Other Human species were less diverse but our kind was able to make very different things out of flint (or whatever other stone they had at hand), also bone tools often, including the needle.
It is not just about the fact that there are tools but also their "style". A disruption in culture would lead to the creation of slightly different methods of creating similar things. This is usually very obvious. I haven't read the research cited for this culture, but I would imagine they might have evidence of continued use of 'flint' making sites (or whatever kind of stone) as well. Survivors entering the area would bring their own tool making styles and traditions with them. People who never made tools would start from first principles and their tools would probably show a progression as their skills progressed over time.
Rittmann, who wrote the first earnest teaching book of volcanology remarked the ignimbrites of Toba "the largest ignimbrite fields". There is in Northern Italy a mighty ignimbrite layer, in which was found the remnants of a small lizard, that died of the eruption.
This is a good reminder that it’s an act of incredible hubris to claim we know exactly what happened before our time based on a relatively small amount of evidence. There’s nothing wiser than claiming “I don’t know”, and in the case of Toba’s effect on the world, we simply just don’t know. And that’s ok. That’s not to say speculation doesn’t have its place, so long as we understand that just because we come to a conclusion, it doesn’t mean it’s the right conclusion.
hmm i’m a little confused as to why sediment from lake malawi is used as a reference, doesn’t the theory already suggest that those region wasn’t as affected as the Asian region??
Ah, the one active super volcano that is bigger than Yellowstone is. I’d also add that the toba eruption wasn’t the largest in the last 2.5 million years, it was the largest in the last 25 million years
It's rather odd that an eruption that size wouldn't significantly cool down the world, the much smaller(but not that small, it was VEI-7 compared to Toba's VEI-8) Campanian Ignimbrite eruption of Campi Flegrei in Italy cooled down the climate and may have been the last straw for the neanderthals at the time (It happened around the same time Neanderthals are said to have gone extinct). When dealing with topics such as volcanic winters, we must understand that the consequences can be terrible for certain lifeforms. The most "recent" global cooling events came from eruptions smaller than the Campanian ignimbrite eruption and even have cooled the climate, caused mass deaths and even famines (Huyinaputina, Tambora, Krakatoa, Pinatubo). PS: I wish the examples of eruptions were better as well, the video takes a "small" eruption from Yellowstone to compare to Toba's gargantuan youngest super eruption instead of taking Yellowstone's largest eruption (Huckleberry Ridge Tuff). There were other examples as well, Taupo in New Zealand had eruptions closer to that eruption.
If you think about it, Mount Toba was earth's huge acne and the earth wanted to pop it, turning it into a crater and the whole mess happening on the rest of its face
VEI8 is not the largest possible for a volcano as you claimed. It is merely the largest which has occurred in the past 20 million years where the VEI scale has been applied. There were stronger volcanos before that.
Cool. I wish you had a video for each continent showing how it came to be where it is from the beginning and the events that precipitated the changes. For example; I just watched some great animation that showed how South American traveled into its current position, then I had to watch all the others, but I don’t know what pushed it there or what caused the sudden lakes to come and go and where did that mountain range come from? India is a fabulous travel adventure but I don’t know what caused that either.
I need to stop telling my brother "awesome facts" I learnt 20 yrs ago on Discovery. I was right to tell about eruptions, but not about human population 🙄
I love how any specialty becomes an even more impressive specialty by adding "paleo". Everything is cooler with paleo added. You're not a climatologist - you're a PALEOclimatologist. Boom.
It's an indication that the person ISNT interest in current events. And the folks studying today aren't experts on 1 million BCE. That is a significant bit of info.

Turtles all the way down.
One overlooked result of the Toba explosion is the complete lack of air travel for tens of thousands of years after the event.

It is not just about the fact that there are tools but also their "style". A disruption in culture would lead to the creation of slightly different methods of creating similar things. This is usually very obvious. I haven't read the research cited for this culture, but I would imagine they might have evidence of continued use of 'flint' making sites (or whatever kind of stone) as well. Survivors entering the area would bring their own tool making styles and traditions with them. People who never made tools would start from first principles and their tools would probably show a progression as their skills progressed over time.
First Steve and now we lose Patrick! :(
Great video though, thanks
Rittmann, who wrote the first earnest teaching book of volcanology remarked the ignimbrites of Toba "the largest ignimbrite fields". There is in Northern Italy a mighty ignimbrite layer, in which was found the remnants of a small lizard, that died of the eruption.
YES YES YES!!!! I know about this volcano and have always wanted y’all to cover it. 😭😭😭
Nobody:
Indonesian 74.000 years ago: "i sense a disturbance in the air"
Congrats, close to 2million subs!
Thanks a lot for the great content!
Very interesting video! Love this channel 😊❤
lmao that lion's face is really squashed at 5:09
Had the Wikipedia page for this open as you uploaded this
Neat
This is a good reminder that it’s an act of incredible hubris to claim we know exactly what happened before our time based on a relatively small amount of evidence. There’s nothing wiser than claiming “I don’t know”, and in the case of Toba’s effect on the world, we simply just don’t know. And that’s ok.
That’s not to say speculation doesn’t have its place, so long as we understand that just because we come to a conclusion, it doesn’t mean it’s the right conclusion.
Thanks for the great video. I love each of these, and cant wait for the next! I especially like the human journey
hmm i’m a little confused as to why sediment from lake malawi is used as a reference, doesn’t the theory already suggest that those region wasn’t as affected as the Asian region??
Love PBS Eons
Great episode
I wasn't expecting Bear Lake to make an appearance lol
It's always a good day when eons releases
Ah, the one active super volcano that is bigger than Yellowstone is. I’d also add that the toba eruption wasn’t the largest in the last 2.5 million years, it was the largest in the last 25 million years
O Toba ta pegando fogo!
Very interesting video, thanks!
Someone needs to activate the reset again.
Please could we get an episode on Dinocrocuta? It’s an amazing animal that needs a video all to itself ❤️
*Googles Dinocrocuta* Oh cool, like a hyena thing... THAT'S AS BIG AS A HUMAN, HOLY CRAP."
@@Cec9e13 yeah, dinocrocuta was OP. I’m sure tierzoo would rate it S+ tier

It's rather odd that an eruption that size wouldn't significantly cool down the world, the much smaller(but not that small, it was VEI-7 compared to Toba's VEI-8) Campanian Ignimbrite eruption of Campi Flegrei in Italy cooled down the climate and may have been the last straw for the neanderthals at the time (It happened around the same time Neanderthals are said to have gone extinct).
When dealing with topics such as volcanic winters, we must understand that the consequences can be terrible for certain lifeforms. The most "recent" global cooling events came from eruptions smaller than the Campanian ignimbrite eruption and even have cooled the climate, caused mass deaths and even famines (Huyinaputina, Tambora, Krakatoa, Pinatubo).
PS: I wish the examples of eruptions were better as well, the video takes a "small" eruption from Yellowstone to compare to Toba's gargantuan youngest super eruption instead of taking Yellowstone's largest eruption (Huckleberry Ridge Tuff). There were other examples as well, Taupo in New Zealand had eruptions closer to that eruption.
The water vapor thing makes sense, it's on an island
I wonder how humans will handle a megavolcano eruption today
Hoarding toilet paper!
Not well
Poorly
There'd be claims 5G or whatever new tech causes volcano eruptions
@@bri1085 you should be worried about strong radio waves going off near you at all times.
Can't wait to see the Eons episode on the footprints discovered in White Sands!
maybe the best channel in the youtube. Congrats!!
This channel kicks ass.
Nothing like a good science debate
can we do megalania
Yay Kallie so glad to see you're Back!!
If you think about it, Mount Toba was earth's huge acne and the earth wanted to pop it, turning it into a crater and the whole mess happening on the rest of its face
VEI8 is not the largest possible for a volcano as you claimed. It is merely the largest which has occurred in the past 20 million years where the VEI scale has been applied. There were stronger volcanos before that.
Great discussion about the tradeoffs
Can you please do a video about the evolution of the brain. From the small bundle of specialized nerves in ancient fish to our complex human brain.
Nice video, thank you!
A cephalopodcast?! Brilliant!💚
Cool. I wish you had a video for each continent showing how it came to be where it is from the beginning and the events that precipitated the changes. For example; I just watched some great animation that showed how South American traveled into its current position, then I had to watch all the others, but I don’t know what pushed it there or what caused the sudden lakes to come and go and where did that mountain range come from? India is a fabulous travel adventure but I don’t know what caused that either.
Tectonic plates.
Idk where exactly you'd find it but the history of the tectonic plates and how they move is what you want to learn.
Great video!
I need to stop telling my brother "awesome facts" I learnt 20 yrs ago on Discovery. I was right to tell about eruptions, but not about human population 🙄
Love this channel 😯☺️
I love how any specialty becomes an even more impressive specialty by adding "paleo". Everything is cooler with paleo added. You're not a climatologist - you're a PALEOclimatologist.
Boom.
It's an indication that the person ISNT interest in current events. And the folks studying today aren't experts on 1 million BCE. That is a significant bit of info.
How will this affect the trout population
Kalie, please don’t get this wrong, but I fall asleep while listening to you. No other programme and presenter relaxes me this much:)
I hope one day you guys make a video about the only extinct order of marine mammals. Desmostylians!
Awesome vid
Thanks!
What was the population dip before Toba then? (@ 2:50)
Eons is always fascinating!
I’d love to see an episode about the Thylacine!
Already made one.
@@Erica-ye7kp well I have a video to go watch!
Loved the video. Not sure, however, how there can be unintended consequences of a volcanic eruption.
God: Damnit, I just wiped out my most promising species. Oh well, I guess I can work with humans.
