This estimate may well be much too high, if the Toba catastrophe theory is accurate. The Toba super-eruption approximately 70000 - 75000 years ago was one of the largest volcanic eruptions of which we have any record. Nearly 3000 cubic kilometers of magma was ejected (some say it could well have been a lot more), with some 800 cubic kilometers of airborne ash. This took place right in the backyard of the human species at the time. Theory proponents suggest that the human population was reduced to a few thousand individuals, rather than the million that might have been expected given a gradual increase in population. So, instead of a million people living 65000 years ago, it may have been less than one hundred thousand.
