"They" also occasionally breed dogs and cats together, but the issue cannot continue the procreation chain. Like Sabertooth, you are laboring under a false assumption that a "species" is anything other than an invention of academics in order to break up the rooms in museums in an orderly manner. Speciation is a stochastic event and you have to understand it stochastically. Two sets of putatively speciated animals become less likely, in various ways, to produce viable offspring over time. There is no huge gap to be jumped over--it's not a binary function, and no one knows what the precise moment of speciation is--it just dribbles slowly away, and the occasional sport proves nothing except that stochastic questions can't be answered exactly.

Scientists in the Emirates said Tuesday that it took two years to perfect the artificial insemination technique necessary to breed Rama's llama mom, a petite 165 pounds, with his overwhelming dad, who weighs in at 990 pounds.
Despite the article's careless use of the word, note that the animals were not "bred" to create the hybrid, and apparently even the artificial insemination involved went far beyond a simple turkey baster. There are effective barriers to interbreeding between the creatures involved, and they are perfectly good and seperate species.
The claim by evolutionists that geographical separation by itself produces new species, that the environment changes "the nature of the beast" has been conclusively proven to be false.
That would be good, as neither evolutionists or biologists in general believe either of those claims. The later would be Lamarkian evolution. As to the former, biologists do not recognize geographically seperated populations as being distinct species unless there is some reason to believe there are isolating mechanisms that would effectively prevent interbreeding even if the populations were brought together. Additionally biologists recognize many cases of sympatric speciation (where speciation occured even without populations being geographically isolated).
Oh, and it was tens of MILLIONS of years that these creatures have been seperated, not thousands. Par for the course for you to get almost everything wrong.
