Michael, it is the subsuming or conflation of founder dispersal speciation
into simply 'founder effect' then dismissing it (via the geneticists
evidence) that I wanted to draw attention to regarding your presentations
of your argument.  Exactly as you've done again above. They're two
different boxes, surely.

Good. Well I might take comfort from the noting that "some experimental
populations develop a small level of reproductive isolation"
