Several organisms from a strain of bacteria infecting patients in a hospital setting inherited a mutation that increased their resistance to the hospitals' antibacterial drugs. Over time, the drug-resistant bacteria increasingly outnumbered the bacteria without the mutation. This best illustrates

Question

The scenario described in the question is an example of natural selection, where the bacteria with the advantageous mutation (increased resistance to antibacterial drugs) have a greater chance of survival and reproduction, leading to an increase in their numbers over time. The other options (neurogenesis, lateralization, neural plasticity) do not apply to this scenario as they are related to brain development and function, not bacterial evolution.
