There are several factors which lead to speciation. Two of them are:
Geographical Isolation
Due to some geographical changes, few members of a species get isolated from other members. Later, this isolated group grows in a different land and eventually evolves as a new species with new adaptations according to its environment. Natural selection and genetic drift have a major role to play in this.

Let’s understand this concept with an example.
Suppose earlier there was a species of flies living on land A. Some of them fed on dead animals. Evidently, there was a flood which washed off the dead animals and the flies feeding on them. Consequently, a few groups of flies get isolated from the other members to another land B. The species on land A and land B are too far to unite. Moreover, the environmental conditions in land B are different from those on the mainland A. The groups of flies which now live inland B start to adapt themselves according to their environmental conditions. Gradually, the individual’s structure and functions alter to give rise to a new species. This is speciation.
The new species are different from the flies in mainland A as well as from the flies who got introduced to land B by the flood. Even if this new species was reintroduced to the mainland A, they would not mate with those flies. New species start to mate amongst themselves. Thus a population of new species arrives.
