Question 3

How does natural selection drive the evolution of antibiotic resistance in bacteria? Explain the roles of genetic variation, environmental pressures, and individual fitness in this process.

Accepted Answer

Natural selection favors the survival and reproduction of individuals with traits that enhance their resistance to antibiotics.

Answer

Natural selection cannot drive the evolution of antibiotic resistance because bacteria reproduce too rapidly.

Answer

Genetic drift alone drives the evolution of antibiotic resistance in bacteria, not natural selection.
