The Toba supervolcano was the biggest explosive eruption of the last 2.5 million years. And humans were around to see it, or at least feel its effects! But what were those effects?
Thanks to Julio Lacerda ( / juliotheartist ) for the reconstructions of the supervolcano (as well as a bunch of other reconstructions used in this episode!)

The remnants of Toba supervolcano is a lake with an island in it. In that island, there is another smaller lake. And in that smaller lake, there is also an island.

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.

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).

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.

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.

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.

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.

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
@LuisAldamiz
@LuisAldamiz 2 жыл бұрын
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.

There's not exactly all that many tools that can be made out of stone. Its mostly knifes, flint, and pointy sticks
@LuisAldamiz
@LuisAldamiz 2 жыл бұрын
@@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.

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.
