Question

Given below are few forces of evolution. Which of the following would be the best combination of primary forces of evolution?

• A. Variation and mutation
• B. Mutation and isolation
• C. Variation and migration
• D. Migration and random genetic drift

Answer 1

The correct option is A Variation and mutation

There are many phenomena which result in the process of evolution and formation of new species. These forces are classified as the primary and secondary forces. The primary forces are most commonly seen which include variation and mutation. The variation is caused by genetic changes and recombination. The mutation is any random change which will lead to evolution.

Thus, the correct answer is option A.
