In every organism, there are differences between individuals. For example, hair color in humans. Bacteria and viruses, being so small, mutate much quicker than humans. One of the individual traits of a virus or bacteria can be resistance to a drug or antibiotic. So as the drug is used, the organisms without the resistance die off while the resistant individuals live. The resistant individuals reproduce, and pass on this resistance to their offspring. Thus, the population increases once again, but this time, all the organisms have the resistance. This is shown clearly with the antibiotics we use, which only stay effective for fighting diseases for 20 to 60 years. After this time, most of the bacteria has mutated to be resistant to the antibiotic, and so will no longer be killed by it.
