That is not evolution, the bacteria did not become a different species. Unless you are one of those people who use evolution for every possible fluctuation in species population. Micro-evolution is the change in population density (Kettlewells moths); macro-evolution is the change of one species to another (different DNA). All you are doing in your experiment is changing the population density, not the population.

Not all evolution leads to speciation.
Evolution is defined as a change in the DNA of a population.
And the DNA of the population in the experiment I set up does change. DNA for proteins vulnerable to heat change to make proteins that are heat resistant all across the bacterial genome. That is evolution.
When I started out all ten plates had the same DNA from the same ONE bacterium, after I finish I would have ten distinct subpopulatins with new and novel DNA configurations that make them resistant to the stress I subjected them to.
