There are several mechanisms of evolution that are generally recognized by evolutionary biologists. Some, of course, act to increase genetic diversity while others act to reduce it.
​
+ mutation
+ gene flow
+ movable elements
+ recombination
- natural selection
- genetic drift
- biased variation
- non-random mating (including sexual selection)
