Microevolution is merely evolution, the change in allele frequency over time in a population of organisms, and all animals do this all the time.Natural selection is always summing up the variation among a population of organisms and selecting those that show survivability and reproductive advantages, even is the selection does no more that stabilize the organisms phenotypes.Look to the evolutionary history of horses or whales to see clear examples of evolution and selection through time.
'Macro-evolution' is not a process in itself. Rather, it is a perspective on the effects of evolution. 'Micro-evolution' is those effects seen from close-up; by 'zooming out' one sees those same results in a wider scope called 'macro-evolution'. All evolution is driven by genetic variation and natural selection.
