Totally correct, brain damage from talking to a curious 10 year old while trying to coax my old man brain into a list. I'd intended to go find out which ice age took the pre-human species down to just a few hundred breeding pairs. Not at my computer right now, will go look that up shortly.
I'm fairly sure you're thinking of the Toba supervolcano. http://en.wikipedia.org/wiki/Toba_catastrophe_theory
