Macroevolutionary dynamics

Macroevolutionary dynamics refer to large-scale evolutionary changes that occur over long periods, such as the emergence of new species, adaptations, or major shifts in the history of life. These processes result from the accumulated genetic changes, environmental influences, and interactions among species. Think of it as the big-picture view of evolution, showing how life diversifies and transforms over millions of years, shaping the rich variety of organisms we see today. It contrasts with microevolution, which involves smaller, short-term changes within populations.
