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).

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.

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 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.

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

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.

@@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.
