My definition is: has it been assigned a binomial name? I'll also accept if the process has started.
The PNAS paper for the first event does not give a binomial. It says:
> We treat the endogamous group as an incipient species because it has been reproductively isolated from sympatric G. fortis for three generations and possibly longer.
I was not aware that this was the accepted common definition of a species.
The second also does not give a binomial. It describes a method to "initiate evolution of reproductive isolation among sympatric populations".
Is that enough to say that there is a new species? If so, I was not aware that the threshold for a species definition was so sensitive.
