Question

Quizplus · Accepted Answer

Natural selection is the best choice, as it is the process by which certain traits are favored in a population due to their increased fitness or ability to survive and reproduce. In the case of mycobacterium tuberculosis, strains that were less virulent or able to cause disease were likely selected for, leading to a reduction in incidence and severity of tuberculosis. This is thought to have occurred in response to increased hygiene and improved living conditions, which made it harder for the more virulent strains to spread. The other choices are not as applicable to the situation in question.
