Actually, Darwin never said that; the phrase came from Herbert Spencer.

You are quite right, however, in that "natural selection" is a much more correct description of the process than "selective breeding." Mea culpa.

All I am attempting to establish is whether or not selective breeding is the mechanism we observe when "adaptation" occurs in microbiology. If it is not, what is the mechanism. You're getting a lot of mileage by arguing about whether or not this "proves" evolution, a step I have deliberately not taken.
