Adaptations to a specific environment allow organisms to survive, according to Darwin. Bacteria that are sensitive to a particular antibiotic die when they come into contact with it. Some bacteria, however, develop resistance to the antibiotic when they have favourable mutations. Bacteria resistant to these types of bacteria can persist and multiply quickly after their competition is eliminated. As a result, the number of them grows. A member of the population may also inherit genes that confer resistance to others. Thus, bacterial people everywhere become resistant to antibiotics.
