According to the Toba link, after the catastrophe, humans would have migrated out of Africa to repopulate the earth, so no death of all Africans there.

Since the Toba event 74kya and a probable North American boloid event about 13,000 years ago, decimated human and other populations and caused significant downturns in worldwide temperature, does anyone have a catastrophic event for the triggering of the last ice age about 125,000 years ago?

"According to the Toba link, after the catastrophe, humans would have migrated out of Africa to repopulate the earth, so no death of all Africans there."

The 'Hobbits' survived the Toba event on near-by Flores Island. Interestingly they disappeared about the time of the comet impact 12-13,000 years ago.
That makes me wonder if there were other pockets of humanity around the world that survived Toba only to succumb to another later event.

IMO, ice ages are caused by large impacts, and end due to gradual thawing by the Sun.
