Answer:
2. macroevolution
Explanation:
Macroevolution refers to the evolutionary processes that lead to the appearance/extinction of groups larger than individual species. Macroevolutionary processes include speciation, species selection and punctuated equilibrium. The punctuated equilibrium processes are represented by phenomena such as those cases described above. These evolutionary processes are concentrated in relatively short speciation phases caused by bursts of evolutionary changes, which are then followed by stages characterized by evolutionary stasis.
