This is certainly not @DennisVenema’s “strongest argument against a bottleneck.”
The strongest argument against a bottleneck, is that a bottleneck of a single mating pair would have left genetic traces well past 10,000 years ago.
And isn’t that pretty much the litmus test? You seem to indicate that if Dennis can’t prove there was never ever a bottleneck of a single mating pair … even further back than 300,000 or 400,000 years ago… then he must be grand-standing.
I would suggest that the grandstanding is going on from another vector… Dennis has convincingly demonstrated that there isn’t a trace of a bottleneck of a single mating pair for as far back as any convincing understanding of “humanity” can be thought to exist. 300,000 years should pretty much cover that, yes?
Since you have returned to this thread less than an hour ago, perhaps you could take a moment to answer my question from quite some time ago:
