If that is so, then it should be the same species.

This is the Californian animal

and the Texan tiger:

So if species get geographically divided, they may evolve differently further on but long as breeding produces fertile offspring, then I think by definition it's the same species. It's not the looks that determines species.

These are the same species too:

LOL!

Out here in CA they try and make them two different ones so that they can restrict land and water use. It's not about the environment, it's about government control.

Higher survival and reproduction rates in a hybrid species may not be an
indication of species survivability. There's a lot to be said for naturally
occuring population control in a species. This is something that, every day,
humans fight against with hosptials and numerous excercises in sounding
alarms about diseases and so on.

Funny enough, the stress that is the result of all the alarms is causing more
deaths via stress disorders such as heart attachs, suicide and wars. So,
naturally occuring population control seems to be pretty hard to shake.
