Point to a biological mechanism in which one species "naturally" reproduces another species? Its logically impossible as the created offspring are reproductions of the original species' DNA.

Nonsense. In no case, other than parthenogenesis, are the offspring of any species which reproduces sexually identical to the parents. You see, your ignorance of biology is betraying you again.
If you think you are identical to your parents, then you are quite incorrect. If you have a brother or sister, is that brother or sister identical to you? Not unless you are identical twins.
You make a common, but regrettable mistake. It is the very fact that reproduction is NOT uniform that leads to the evolution of species.
Your other miscomprehension is that a single reproductive incident can produce a new species. That is simply not the case, and nothing in the theory of evolution teaches that.
Speciation is not a one-time event. By the time a new species emerges a long period of slow alterations has taken place over many, many generations. Once it emerges, the new species can no longer reproduce (in most cases) with the predecessor species.
Please do read something about the theory of evolution, written by someone in the field. Once you do that, you may understand what the theory is. Until you understand that, you will continue to make these simple errors.

It's called "mutation."
> the created offspring are reproductions of the original species' DNA.
So you are your mom's clone? Or your dad's? Or are you slightly genetically different from both?
