Microevolution and Macroevolution Microevolution is a inherited change in a population within the same species but this does not result in a new species. There are four factors that contribute to microevolution: mutation‚ gene flow‚ genetic drift‚ and natural selection. A mutation is generally a random change in the DNA. So for example‚ if a species of birds start developing shorter bills‚ then that is a genetic change. Gene flow is when a population migrates to a different area. The birds might
