Macroevolution comprises the evolutionary processes and patterns which occur at and above the species level. [1][2][3] In contrast, microevolution is evolution occurring within the population (s) of a …

Macroevolution encompasses the grandest trends and transformations in evolution, such as the origin of mammals and the radiation of flowering plants. Macroevolutionary patterns are generally what we …

Nov 10, 2025 · Macroevolution is defined as evolutionary change that takes place at or above the level of the species. It tracks the emergence, persistence, and decline of higher taxonomic groups, such …

Jul 23, 2025 · While microevolution focuses on individual genetic changes within a population, macroevolution examines how these accumulated changes, over immense spans of time, construct …

May 30, 2023 · In macroevolution, we are drawn to documenting and explaining variation—including variation in diversification rates through time and between lineages, variation in the rates of …

Jun 3, 2019 · One significant and remaining challenge in the philosophy of macroevolution is to work out how the various ideas about macroevolution surveyed above may or may not fit together.

Jul 10, 2023 · We highlight four major questions of evolutionary biology whose solutions require conceptual bridges between micro and macroevolution.

Approaches to macroevolution require integration of its two fundamental components, i.e. the origin and the sorting of variation, in a hierarchical framework. Macroevolution occurs in multiple currencies that …

Apr 12, 2024 · Macroevolution refers to large-scale evolutionary changes that occur over extended periods, resulting in the formation of new species, genera, families, and higher taxonomic groups.

Species are real biological individuals and abiotic factors impact the future course of evolution. Beyond observation, when the explanation of macroevolution is the goal, we need both evidence and theory …
