There are different types of speciation, such as the following, allopatric speciation. Allopatric speciation is just a fancy name for speciation by geographic isolation. EXAMPLE of allopatric speciation:
1. There are two forests that are separated by a mountain range. However, they are connected by a valley in the mountain range. There is a species of monkeys happily mating and breeding throughout these two forests.
2. However, one day, there was a massive earthquake and a landslide caused a huge pile of rocks to fall into the valley, cutting off the contact between the two forests. Now the monkeys in the two different forests are cut off from one another and can no longer interbreed with the monkeys on the other side of the mountain range.
3. Assuming that the forests on either side of the mountain range have slightly different ecological conditions, the behaviors or features of the monkeys on either side might change. For example, some of the monkeys could develop longer tails or thicker fur, while the other develops a different fur colour or have thicker skin. Their behaviors can change as well, maybe the monkeys on one side become nocturnal or the monkeys on the other side develop different mating habits.
4. A few generations later, another earthquake clears the rocks, and the connection between the two forests is restored. However, the monkeys on either side have already adapted to their own ecological conditions and their lineages are no longer the same, therefore they cannot mate.
5. However, if they somehow do find a way to mate, they offspring that they produce would not be fertile.
In this kind of speciation, something HAS to prevent the species from mating with each other regularly.
SO BASICALLY:
If a species is separated from the other side,
the species will start to divide.
They will slowly start to change,
while they are still blocked by the mountain range.
Once the rocks come down,
two different species will be found.
It will be sad for them then,
cause they will never mate again.
