The processes of Macroevolution and microevolution are essentially the same. The Diverse timelines represent different manifestations of the same evolutionary process. The Large-scale changes that identify new species or groups of organisms can result from microevolutionary processes that take place over thousands or millions of years.
The Macroevolution is the term used to describe significant changes that take place over a long period of time, like the emergence of new species and social groups. Small-scale changes that occur in populations over shorter durations and have an impact on just one or a few genes are referred to as the microevolution.
