Question

happens slowly over time only occurs below the species level is any change in the DNA of an organism can be caused by genetic drift can be caused by natural selection_____________.

Answer 1

Answer:

The correct answer is - microevolution.

Explanation:

Microevolution is the very small evolutionary change specially allele frequencies on the level of species that occurs slowly over period of time. These changes occurs on the level of DNA or genetic level.

These evolution can be caused by the natural selection process or genetic drift over the generation of the species or population over period of the time. It is the study of the evolution that occurred on level of separated gene pool.

Thus, the correct answer is- microevolution.
