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 single species. In other words, microevolution is the scale of evolution that is limited to intraspecific (within-species) variation, while macroevolution extends to interspecific (between-species) variation.[4] The evolution of new species (speciation) is an example of macroevolution. This is the common definition for 'macroevolution' used by contemporary scientists.[a][b][c][d][e][f][g][h][i] Although, the exact usage of the term has varied throughout history.[4][10][11]
