[Oberon]

You realize that the strictest definition of a species is the inability to breed with predecessors, right? Even by the strictest definition, they have speciated.

Really? An inability to breed with precedessors?

Do you mean to say that sperm from one population won't fertilize an egg from the other population and produce a viable offspring, or do you mean that they simply don't crossbreed?

If it's true, it's momentous. Show me, please...?

[Dante Alighieri]

Momentous? Hardly.
