Antibiotic resistance is evolution in action

Surviving bacteria pass on genes that let them withstand the drug Bacteria vary in their susceptibility to an antibiotic, and treating an infection kills the vulnerable cells first. The survivors multiply, so the population shifts toward resistance within a few generations. Resistance genes also spread sideways between species on small loops of DNA called plasmids. It sits in Mondo's science collection, one of 200 facts that each trace back to the reference below.
