Speciation is the formation of new species from pre-existing species through variations.

The factors that lead to speciation are:

1. Genetic drift and natural selection

2. Reproductive isolation for a long time

3. Geographical isolation

4. Action of environmental factors on the isolated population.

Hope this helps.
