At the end of the day, early humans are very intelligent and very adaptable (unlike dinosaurs). I am not saying that no natural event could wipe out almost all humans, but I think it would take far more than a mega volcanic eruption. |
It's not a theory. It's a genetic fact. Geneticists have long known of the "Genetic Bottleneck". However, I've had a problem with the numbers bantied about. Figures range from 2,000 to 20,000 human survivors.
Early humans have always had a habit of surprising us. I don't know why this should be any different. I'd be more comfortable with a figure like 100,000 survivors. The Spaniard in the works,IMHO, is the Neanderthal. If we were reduced to less than a 100,000, what happened to them?
The eruption itself left an ash layer 30 ft deep in many places. What came after was the killer, A nuclear winter that some say could have lasted as long as 100 years.

What they are hypothesizing is that the tool technology found under the ash layer is unchanged in the habitation sites found over the ash layer. Meaning the folks that made the tools under the ash were the same folks who made the tools over the ash.

humans were already in arabia 125000 years ago, so yeah its possible that they were in India 75,000 years ago

The depositional position of the tephra in the Jurreru River Valley, to gether with new chronometric and geochemical evidence, indicates that the ash is a product of the 74,000 year old YTT event (Petraglia et al., 2007). The recovery of Middle Paleolithic assemblages in dated deposits below and above the ash provides the first firm archaeological association, helping to resolve some of the uncertainty about archaeological associations in India. The recovery of Middle Paleolithic industries without major technological changes after the ashfall, indicate that populations survived the super-eruption. We have suggested, based on a variety of datasets, that modern humans were present in the Indian sub continent before the super-eruption, and that these populations survived this event.
