Question

which term names the most powerful evolutionary force in large populations over time? natural selection genetic recombination migration mutation

Explanation:

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring. In large populations over time, it acts as a powerful evolutionary force by favoring traits that enhance survival and reproduction. Genetic recombination mainly shuffles existing genetic material. Migration (gene - flow) and mutation introduce new genetic variation but are often less powerful than natural selection in shaping the overall evolutionary trajectory of large populations over extended periods.
