Similar to the application of insecticide and conferred resistance of pests to insecticide, antibiotic resistance in bacterial populations is derived through the process of natural selection. Explain the process of natural selection, with specific reference to how bacterial populations may become antibiotic resistant.

Natural selection is the process by which traits become more or less common due to organisms interactions with the environment. Evolution, a fundamental concept within natural selection, is the change in genetic characteristics over time. Bacteria populations come in contact with antibiotics and inherit traits to improve their survival; which gradually modifies their genetic characteristics to resist antibiotics. These genes are then passed from parent to offspring making entire bacteria populations resistant to antibiotics.
