Term
Macroevolution is the process of the ecolution of new tazonomic groups through evolution. It differes from microevolution in that microevolution refers only to changes that occur in populations from generation to generation no new species or other taxonimic groups need arise in the course of microevolution. Microevolution occurs on a small scale, whereas macroevolution concerns the "bigger picture."
