The bacteria in the example evolved because of natural selection. Natural selection is the process by which individuals with traits that are better suited to their environment reproduce more successfully than others, leading to a change in the genetic makeup of a population over time. Gene flow refers to the transfer of genetic material between populations, while genetic drift is a random process that can cause changes in allele frequencies in a population, particularly in small populations.
