What is the difference between macroevolution and microevolution

Microevolution is evolution on a scale of separated gene pools .

Macroevolution studies focus on change that occurs in contrast with Microevolution

I hope that's help !

Microevolution happens on a small scale (within a single population), while macroevolution happens on a scale that transcends the boundaries of a single species. Despite their differences, evolution at both of these levels relies on the same, established mechanisms of evolutionary change: mutation.

thermophiles, notice the prefix thermo.
