Macroevolution refers to large-scale evolutionary changes that occur over long periods of time, typically resulting in the formation of new species or higher taxonomic groups. It encompasses processes such as speciation, extinction, and the diversification of life forms.
The six patterns of macroevolution are stasis, gradualism, punctuated equilibrium, adaptive radiation, convergent evolution, and extinction.
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 is an example of macroevolution. The slow transition of land tetrapods to whales, the transition of small, many toed creatures into horses. These are not linear so much as branching progressions with the occasional dead end. Darwin's finches are a modern example of macroevolution by adaptive radiation.speciationBirds are reptiles.
An example of macroevolution is the evolution of whales from land-dwelling mammals to fully aquatic creatures over millions of years. This involves significant genetic and morphological changes at the species level, resulting in new species with distinct characteristics.
The general term for large-scale evolutionary changes that take place over long periods of time is macroevolution. It refers to the processes that result in the formation of new species and higher taxonomic groups.
The terms macroevolution and microevolution were first coined in 1927 by the Russian entomologist Philipchenko. Macroevolution is the term now used to refer to any evolutionary change at or above the level of species, such as the splitting of a species into two or the change of a species over time into another species. Microevolution refers to any evolutionary change below the level of species, and can also apply to changes that are not genetic.Creationists often assert that macroevolution is not proven, even if microevolution is, apparently meaning that whenever evolution is observed it is microevolution, never macroevolution. These claims are considered a misuse of authentic scientific terms. Macro Evolution is a theory; it is also a fact.For more information, please visit: http://christianity.answers.com/theology/the-story-of-creation
microevolution can lead to macroevolution
to what does the term coed refer
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 six patterns of macroevolution are stasis, gradualism, punctuated equilibrium, adaptive radiation, convergent evolution, and extinction.
Macroevolution The development of a new species is called speciation.

The term used to refer to someone with a Ph.D. is "doctor."
The term used to refer to a quantum of light is a photon.
Microevolution can lead to Microevolution
The term extraterrestrial can be adjective or noun. In adjective case, the term extraterrestrial refer occurring or existing beyond the earth's atmosphere. In noun case, the term extraterrestrial refer being from the beyond the earth's atmosphere.
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.
