Speciation is the evolution of reproductive isolation among once interbreeding population.
Factors which can lead to speciation are:
- Genetic drift: Over generations, genetic drift may accumulate which leads to speciation.
- Natural selection: Natural selection may work differently in different location which may give rise to speciation.
- Severe DNA change.
- A variation may occur which does not allow sexual act between two groups.
