Question

Quizplus · Accepted Answer

Natural selection likely reduced the prevalence of tuberculosis in the early twentieth century by favoring individuals with genetic factors that conferred resistance to the disease. This may have been due to factors such as improved nutrition and hygiene, as well as increased exposure to less virulent strains of the tuberculosis bacterium. Other factors like mutation, migration, nonrandom mating, and genetic drift are less likely to have played a significant role in reducing tuberculosis incidence and virulence.
