Macroevolution is the collection of events of evolutionary changes that are above the level of species and it involves diverse changes in the forms and functions which are capable of producing new species and more taxa. The macroevolution focuses on the tree of life rather than a species. The greatest trends and variations in evolution are encompassed by macroevolution.
The patterns of macroevolution include the large-scale history of life. The evidence for life history is provided by certain sources like geology, fossils, and living organisms. The evolutionary mechanisms such as mutation, migration, immigration, natural selection, etc. produce drastic evolutionary changes over the passage of time.
