Explain antibiotic resistance observed in light of Darwinian selection theory.

Solution
According to the Darwinian selection theory.
When the bacteria are grown in culture that have a certain antibiotic, most of the bacteria are killed but some of them develop a mutation which provides resistance against the antibiotic . With time the bacterial population having antibiotic resistance will increase and outgrow the population of the non-resistant bacteria. Thus a new species that has antibiotic resistance will be selected against the original one.
