Geographic isolation leading to reproductive isolation.
Explanation:
Suppose members of a species get geographically isolated that is separeted by natural barriers like mountains,rivers,or sea into 2 groups,hence there would be no exchange of genes among both groups.Now for million years when both groups will produce generation after generation in a totally different environment then there would be a gradual change gene frequency leading to genetic drift.
