Which of the following has evolved mainly as a result of artificial selection?
Correct answer: B. Increased production of antibiotics by the fungus penicillium species
- A. Darker coloring of prepared moth near industrial areas
- B. Increased production of antibiotics by the fungus penicillium species
- C. Increased resistance of houseflies to the insecticide DDT
- D. Increased resistance of lichens to the heavy metals on tree bark around mine workings

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
