There are those who claim that the theory of evolution cannot be true because the apes, which are supposed to be closely related to humans, do not likewise share the same large brains, capacity for complicated speech, and tool-making capability. They reason that if these features are generally beneficial, then the apes should have evolved them as well. Which of these provides the best argument against this mis-conception?
A. Advantageous alleles do not arise on demand.
B. A population's evolution is limited by their environment.
C. Adaptations are often compromises.
D. Evolution can be influenced by environmental change.
