“However, there is wide disagreement about how early human were affected and whether large parts of the population were wiped out by the blast.”

Aren’t there theories that Toba wiped out all but about 12,000 of the human population of the planet?

There’s some groundless speculation to that effect. :’)

This (74,000 years ago) predates human existance by about 68,000 years...how could there be 12,000 of the human population as survivors? :)

Yes, there are such theories. Also, the crater left by Toba is about 16 by 65 miles.
