Just out of morbid curiosity, what are the others?
I can't think of any natural disasters in that magnitude over the last three centuries. The Lisbon earthquake killed on 50,000, but it is memorable because so many people were killed when their churches collapsed. Karatoa, maybe?
Man-made catatrophies don't match up. The Dresden bombing killed IIRC 135,000 -- more than either the Hiroshima or Nagasaki bombs. The firebombing of Toyko is in that range too. The Battle of the Somme was something like 50,000-60,000.

Question: when a new species evolves, its genetic makup has to be somewhat limited, not so? It is not clear to me that our own lack of genetic diversity vis-a-vis the chimps, for example, is not because we are a realtively new species compared to them even though the chart on the link suggests that chimps are a newer species than humans.
Still, it is interesting that the volcanic eruption of Toba brought on a new ice age. If there was a mass extinction of humans at that time, I think it had to occur in the immediate years after the erruption caused by sever cold. The chart indicates that the population collapse occured over thousands of years. I find that to be unlikely. |
Again, the paraphrase my old ecology prof, the level of genetic diversity (especially mitochondrial which is only passed on from the mother and mutates at a pretty predictable rate) is low enough to suggest a pretty big bottle-neck at around the time of the Toba eruption. It is not at all consistent with the existance of a relatively large human population all the way back to the older homo sapien remains that we have.
Also the chart you're looking at is just a schematic, we obviously don't when and how fast the human population dropped to cause the bottleneck. Again, all we basically know is:
A. Before the toba eruption there were human populations in the mid-east area and after the toba eruption is seems that humans were knocked back to Africa.
B. Due to the diversity of human mitochondrial DNA it was probable that the human population bottlenecked hard at around the time of the toba eruption. Other scenarios are possible, such as a longer and more gentle bottleneck, but having the toba eruption and the subsequent ice age resulting in a bottle neck in the human population seems the most probable.
C. The toba eruption was very very very big.
