What is macroevolution?
genetic changes among and within populations
major changes in populations over a long time

minor changes in populations over a long time
1 answer
Macroevolution refers to major changes in populations over a long period of time, leading to the formation of new species or higher taxa. This can involve the emergence of new characteristics, adaptations, and genetic diversity at a larger scale than microevolution, which focuses on changes in allele frequencies within populations.
