We have discussed a number of examples that explain how evolution functions, factors that influence rates of change, as well as the specific processes that give rise to the diversity of evolutionary outcomes seen in organisms. With this in mind, which processes are believed to have the greatest influence on rates of evolutionary change?

Genetic drift promoting static allele frequencies.

Both natural selection and genetic drift, tending to act in opposing directions: one process favors increasing genetic diversity, and doing so quite rapidly, and the other favors a slower rate of decreasing diversity.

None of the options.

Natural selection promoting fast mutation rates.

Both natural selection and genetic drift, acting in the same direction to either increase or decrease mutation rates.

Solution

Ans.

Natural selection is the most critical evolutionary process that leads to changes in allelic frequencies and genetic drift is a random change in allelic frequencies over the generations.

so option C is more appropriate than others
