Yes it is evolution.......evolution is the change in gene frequencies of a population over time. So it is evolution.....
You could make an argument that it isn't speciation. You would be relying heavily on a lab-based biological species concept......(which means you might have to consider a Ball and a Angolan python the same species)...would a wolf in the wild really mate with a domesticated dog?
Bottom line.....Speciation and Evolution are not the same thing.....
