QUESTION 10
One of the reasons that natural selection works on populations rather than on individuals is that _____________.
Natural selection only brings about macroevolution (which only applies to populations), and not microevolution (which only applies to individuals)
populations are too large for natural selection to have an effect
populations have different genes than do individuals
individuals can develop new alleles, but populations cannot
A population has many generations over which the allele frequency can change, whereas an individual's alleles don't change
