Question

Quizplus · Accepted Answer

HIV evolving resistance to antiviral medications is an example of microevolution because it involves changes in the genetic makeup of the virus population over a relatively short time period. This is a small-scale evolutionary change that occurs within a species or population, as opposed to macroevolution which involves larger-scale changes such as the emergence of new species. A, B, and D are examples of macroevolutionary changes.
