Do you actually believe that the study that was done in the 50's on Drosophila Paulistorum shows a legitimate speciation event?

Tell me why it isn't.

And you might consider addressing some of the other examples of speciation too. I rather like the copper-tolerant Mimulus.

Tell me why it isn't.

From the link I posted earlier (453):

Boxhorn is saying that two fruit flies which he asserts are different species, successfully mate and produce offspring (thereby proving conclusively that they are not different species but the same species.) He calls the offspring 'hybrids' in an attempt to smuggle their 'different' species status in by the back door. Later some of the offspring exhibit 'behavioural isolation' (like Chihuahuas and Great Danes) but this is irrelevant as a sign of species status. So where, in all this, is there an instance of speciation -- or one species turning into another?
