 C. New generations are better suited to survive than previous generations.
 D. Evolution can only cause small changes to a species.

C. New generations are better suited to survive than previous generations.

Explanation:

According to the evolutionary theory proposed by Darwin, evolution can be defined as a gradual process by which organisms change over time. Natural selection is the mechanism by which evolution occurs: organisms exhibit variation that may be passed from one generation to the next, and part of this variation confers an adaptive advantage. The organisms that are better adapted to their environment will have more chances to survive and reproduce, and they will pass these phenotypic changes to the next generation. At the species level, these phenotypic changes between generations are gradual, it is for that reason that evolution is a slow gradual process. In consequence, it is expected that new generations are better adapted to survive in the same environmental conditions.
