Question

The bacteria in the example evolved because of...


gene flow


genetic drift


natural selection

Answer 1

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.
