What are the 6 patterns of macroevolution?
The six patterns of macroevolution are stasis, gradualism, punctuated equilibrium, adaptive radiation, convergent evolution, and extinction.
What is an an example of macroevolution?
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.
What is the answer for which of the is an example of macroevolution?
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.
Are there complicated links between microevolution and macroevolution?
Microevolution refers to small changes in gene frequency within a population over a short period, while macroevolution involves larger scale changes resulting in the formation of new species over long periods. The two are connected, as microevolutionary processes, such as genetic mutations and natural selection, can lead to accumulation of changes that drive macroevolutionary patterns seen in the history of life on Earth. However, the exact relationship and mechanisms linking micro- and macroevolution are still under scientific investigation.
How do Darwin's findings point to micro evolution but not macroevolution?
Darwin's findings, such as natural selection, provide evidence for microevolution, which involves changes within a species over time. However, they do not offer direct evidence for macroevolution, which involves the formation of new species or higher taxa over long periods. Macroevolution typically requires additional mechanisms, like genetic mutations and genetic drift, to account for larger-scale changes.
Which statements about microevolution and macroevolution is true?
microevolution can lead to macroevolution

Macroevolution can be described as?
the development of dramatically novel designs, such as wings for flight
Is natural selection an example of macroevolution?
No, natural selection is the mechanism that drivesevolution.
Is genetic drift an example of macroevolution?
No, genetic drift is an example of microevolution.

Is macroevolution both a fact and theory?
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
