A. take advantage of the fact that all mutations affect the fitness of an organism.
B. take advantage of the fact that all mutations happen at a steady rate.
C. take advantage of the fact that only neutral mutations do not happen at a steady rate.
D. take advantage of known mutation rates to estimate how long ago organisms shared a common ancestor.

Answer 1

D. take advantage of known mutation rates to estimate... please correct me if I'm wrong. I'm studying this right and I would love to know if I'm wrong so I can know what's its not when I take my test, that's if this question on my test,but anyhow I still prefer to know

Answer 2

The molecular clock is a technique used involving the mutation rate of biomolecules to deduce when in prehistoric times have two or more lifeforms diverged.
