If evolution is descent with modification applied to life on Earth‚ then microevolution can be called the small‚ measurable evolutionary changes within a population while macroevolution is large evolutionary change over long periods of time - short term and long term/big picture evolution‚ essentially. Microevolution works on a single population’s genetics and could be said to be the status quo of evolution that occurs consistently and universally while macroevolution occurs over many years or as
