difference between Micro and macro evolution

[Jovian]

Microevolution is a part of macroevolution, and both are a part of evolution. Microevolution is small incremental changes within a species or population over successive generations. When those incremental changes between two or more seperated gene pools within a species mount up over many generations to the point they can no longer interbreed, that is when microevolution becomes macroevolution. Macroevolution is when microevolution reaches the point of speciation and above. Those gene pools will continue to drift apart over many more generations until they have diverged into many new species, genera, tribes, families and so on. The different gene pools will continue to diverge as long as each lineage survives, and it will some day get to a point after thousands upon thousands of generations where these descendants will be completely different from their now distant ancestors.
