Microevolution occurs within populations. Macroevolution is thought of as the patterns of change that occur between taxa. Which is an example of speciation?

a. microevolution

b. macroevolution

c. both

d. neither

Neither of them is an example of evolution. Evolution is a consequence of these changes.

Explanation:

Microevolution refers to changes produced at an inferior level than species. In genetics, microevolution is the change in the allelic frequency perceptible in a few generations. Most of these changes are naturally produced by mutation, natural selection, genetic flux, genetic drift. Macroevolution refers to evolutive changes in big scales that break the limits of species, making a place to new species or even affecting superior taxonomic levels.

All the processes that produce macroevolution are the same as those that produce microevolution. These are mutation, natural selection, migration, genetic drift. The only difference is the scale.
