How does warfarin resistance in rats demonstrate natural selection?
warfarin were a poison for rats, rats that are resistance to this poison would survive

How does bacterial resistance to antibiotics demonstrate natural selection?
the resistant bacteria will survive despite if antibiotics are used and the non-resistant bacteria will die
