Answer
Inherited resistance. Luria's research demonstrated that bacteria can inherit resistance to antibiotics through genetic mutations. By exposing bacteria to antibiotics and then isolating the survivors, he found that the offspring of these survivors exhibited increased resistance to the same antibiotic. This discovery challenged the prevailing belief that bacteria acquired resistance only through gradual adaptation.
