When the organism of the populations evolve in the time course of evolution in such a way that they form new species and are no longer capable of interbreeding then this process is known as speciation.
Speciation can occur both naturally and artificially.
Artificial speciation is the process of speciation that is triggered by the deliberate acts of human beings to form new species.
Since the controlled mating in the lab or in animal husbandry involves selective breeding of the individuals to have species with the characters of interest this is an example fo artificial speciation.
The Miller–Urey experiment (or Miller experiment) was a chemical experiment that simulated the conditions thought at the time to be present on the early Earth, and tested the chemical origin of life under those conditions. The experiment supported Alexander Oparin's and J. B. S.
