"The current view is not a founder pair but a founder small population in the 10K range." - TG
Is this consistent with the idea of 'polygenism,' even if it doesn't address the 'multiregional hypothesis'? Does it not contradict the idea of 'monogenism'?
Can you forgive my SoS question: whose view is the 'current view' and the 'present notion'? Is this what 'normal science' says? (And for a non-NS) Which fields does the 'current view' mainly draw upon?
It seems to me that David C.'s post carefully left open more than one option, which I quite appreciate, not being a 'scientist' in a field that speaks about bottlenecks (though 'probka' means 'bottleneck/traffic jam' in Russian) or near extinction events. The consequences of a 'founder small population' instead of a 'founder pair' in sociology is significant, though not commonly discussed in the literature.

Individually, of course, but this isn't the present notion of Homo
sapiens speciation, is it? The current view is not a founder pair but
a founder small population in the 10K range. I have also heard a
recent report of a 2K bottleneck and near extinction event (drought
caused) about 70,000 years through a Scientific American podcast.
Haven't had a chance to follow up on the details.
