a. common ancestry
b. asexual reproduction
c. overproduction and competition
d. genetic variation
e. unequal reproductive success
f. environmental stability

Explanation:

• A. Common ancestry is a result, not a driving force.
• B. Asexual reproduction can limit variation, not a main driving force like sexual reproduction.
• C. Over - production leads to competition for resources, a key aspect of natural selection.
• D. Genetic variation provides the raw material for natural selection to act upon.
• E. Unequal reproductive success is the mechanism by which natural selection occurs.
• F. Environmental stability doesn't drive evolution by natural selection; environmental change does.

Answer:

C. overproduction and competition
D. genetic variation
E. unequal reproductive success
