The six patterns of macroevolution are stasis, gradualism, punctuated equilibrium, adaptive radiation, convergent evolution, and extinction.
Microevolution is small evolutionary changes. Macroevolution is change above the specie level. Biologists debate if this process even exists. Some say they are fundamentally the same thing. It seems that macroevolution is the evolution of evolution. That sounds complicated.
Macroevolution is evolution on a scale of separated gene pools. Macroevolutionary studies focus on change that occurs at or above the level of species, in contrast with microevolution, which refers to smaller evolutionary changes
Microevolution is not part of macroevolution. Microevolution involves small-scale changes within a species over a shorter period of time, while macroevolution involves larger scale changes that lead to the formation of new species over a longer period of time.
Speciation can occur through mechanisms like allopatric or sympatric isolation, where populations become reproductively isolated and diverge genetically over time. Macroevolution, which refers to larger-scale evolutionary patterns and processes, can be driven by factors like natural selection, genetic drift, and mutations that accumulate over millions of years, leading to the emergence of new species and diversity of life forms.
Scientists use various methods to study macroevolution, including fossil analysis, molecular genetics, comparative anatomy, and biogeography. By examining the patterns of change in species over long periods of time, scientists can gain insights into the processes driving macroevolutionary trends.
microevolution can lead to macroevolution
Topics of macroevolution include speciation (the process by which new species arise), adaptive radiation (the diversification of a group of organisms into different forms), evolutionary trends (long-term patterns of change in a lineage), and extinction events (massive die-offs affecting a wide range of species).

The fossil record
the development of dramatically novel designs, such as wings for flight
No, natural selection is the mechanism that drivesevolution.
