Are you actually claiming that camels and llamas are the same species? Something like different breeds of dog?
As I have said, if you cannot define, you cannot give proof of it. Since there is no adequate definition of species, no such proof can be given. The experiment done shows that llamas and camels are close enough that they can produce offspring. This is a strong indication of individuals being of the same species. Since however the experiment is recent and we do not know of the ability of the llama-camel offspring to produce offspring, we do not know if the relationship is like a a mule or not.
What the experiment does show however is that species are not as mutable as evolutionists would like us to think. 30-40 million years and the two branches can still mate shows that the evolution claimed by evolutionists from small mammals to man in 100-120 million years is clearly impossible.
