I guess you guys just can't see how laughable the idea is that inability to interbreed is the definition of speciation. The usual situation must be a condition of genetic reduction to depletion which in itself could be the cause of inability to interbreed, just by genetic mismatch, the furthest possible thing from anything deserving the term "speciation." It's really astonishing how you all go on talking about absurdities with a straight face.
Well, set us straight. I'd have said that when a polyploid hybrid between
Helianthus annuus and
Helianthus petiolaris is able to breed with others of its kind but not with either of its parent species, this constitutes the production of a new species. But if it is not, then pray tell us, Faith, which
old species does it belong to, and by what criterion?
Oh, and "probed" was a typo, I meant "proved."
I know that. The word that made me laugh was "logically", which you spelled perfectly but used incorrectly.
