Re: not genetic compatibility, genetic isolation
You're basically claiming that hundreds of species that never interbreed in the wild are the same species.
​
An example of this problem would be the Liger or the Tion. Tiger's and Lion's are considered seperate species but mating between them can produce a 'viable' though infertile offspring.
​
Or for that matter, horses and donkeys and mules.
