I guess I thought that what I was 'ridiculing' was the center of origin
since it was this that I was characterizing as a fantasy. Yes it does
seem that identification of the imagined center of origin is rather ad
hoc in relying on the oldest fossil which has no necessary link with
place of origin (the link is imagined).

Perhaps, but whether its good science in any particular case is another
matter. I would argue that dispersalism (Darwinian centers of origin
theory) is not much of a science despite its popularity.
