Macroevolution is larger scale evolution above the species level. It happens over a longer period of time than microevolution. For example, microevolution can cause small adaptations within a species, but macroevolution causes more noticeable anatomical changes that give rise to new species and new groups of organisms.
There is no real separation between micro- and macroevolution. Microevolution, over time, translates into macroevolution.
Speciation of any kind. 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.
A) the origin of new species
B) The origin of evolutionary novelty
C) explosive diversification following some evolutionary breakthrough
D) mass extinctions
E) all of the above
E all of the above
Macro-evolution is a large scale perspective on the effects of evolution, just as micro-evolution is a small scale perspective on the effects of evolution. Evolution produces continuous divergence. Divergence between the genome of one generation of a population and a specific ancestral genome, and divergence between sibling branches stemming from the same ancestor. If one focuses on the variation and divergence occurring within a species, it is micro-evolution that one is studying. When one zooms out and sees the divergence continue beyond the point of speciation, it is macro-evolution that one sees. The process and the effects it causes are the same; the perspective differs.
Macro evolution is major evolutionary change that occurs over a long period of time.
Birds are thought to be direct descendents of reptiles
Example of a solid: ice Example of a liquid: water Example of a gas: steam
what is the example of division
this is an example of combustibility.
Silver is an example of an element.
what is an example of homogeneous mixture?
No, genetic drift is an example of microevolution.

macroevolution is the evolution of one species to another.
No, natural selection is the mechanism that drivesevolution.

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.
