Question

Which of the following best describes the large evolutionary changes that take place of thousands to millions of years and produce evolutionary novelties such as feathers in birds and large brain sizes in hominids? (type 1, 2 or 3 in the blank).

1. microevolution
2. macroevolution
3. genetic divergence

Answer 1

2. macroevolution

Step-by-step 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.
