The given statement: macroevolution occurs within a population is false.
Macroevolution happens at a level above the level of species. Microevolution involves changes within population or species in contrast to macroevolution. The difference between the macroevolution and microevolution occurs is the time frame of the evolutionary process. Macroevolution refers to a large scale evolution and describes the common ancestry between the living organisms. It is used to assess the largest trends and transformations in evolution.
