It's been done, many times.
Someone has observed the rise of a new specie in the lab? Funny, I missed that bit of news.

Cool. Where's the cat/dog transitional form that came out of the laboratory?
What the laboratory has done is demonstrate the process of variation within a species and the methods by which it can occur (gene transfer, mutation, etc.)
The idea of the origin of species has never been experimentally verified.
