Organisms' DNA mutates. Of course the genetic makeup of the yeast would change over time, no matter what you did with it. We know this from a wealth of studies already. Science is way past that point and it's about time the general populace catches up.
The interesting thing here is not actually that stuff evolves. Micro organisms (and life in general) evolve in the labs and elsewhere and that's nothing new. The interesting thing here is the evolution of the multicellular trait. Many have thought it a very difficult trait to achieve, but this scientist and his study shows how quickly it can happen in yeast and that can tell us something about how the trait first appeared in other lineages.
I find it a bit difficult to respond to you because I'm not sure we're on the same page. For example, I don't know to what extent you understand evolution. Perhaps you believe genetic mutations are very rare?
