B. Your taste in music changes dramatically between middle school and high school.
C. A young man's muscles increase in strength and bulk after he starts lifting weights.

B. All of these
C. Environment stresses on a population
D. Increase in adaptive traits over time

Question 3: Select all that apply.
Which of the following ideas would fit within the theory of evolution as proposed by Charles Darwin and as accepted today?

B. The genetic makeup of a population changes over generations of time.
C. The genetic makeup of an individual changes in response to the environment.
D. The genetic makeup of a population changes seasonally.
