First Stage: Separation
Speciation usually begins when a part of a population becomes separated from the rest of their species.
Separation can happen in three different ways by having a newly formed canyon, mountain range, or from a lake.
Separation's role in evolution is to help organisms' adapt in their new environment so they are best suited for the environment they got separated too.
In sharks separation occurs when they get separated from tidal waves, tsunamis, and underground sea canyons, and more.
They can get separated through these natural movements in Earth because of how tidal waves can move sharks away from each other, tsunamis may move many sharks to different areas, and underground sea canyons can block sharks from their habitat.u

Second Stage: Adaptation
Adaptation in speciation is quite similar, though the groups may evolve different sets of traits if the environmental conditions differ for each group.
Adaptation's role in speciation is to help the groups adapt to their new environments, or help them adjust to their new environment.
Examples for adaptations in sharks is the great whit sharks' skin called dermal denticles, which protect the skin from damage and are replaced continually the dermal denticles have ridges which reduce drag and noise while the sharks are swimming , so their prey wont be able to notice them very easily.
The great white sharks' color is also an adaptation, because its color is very difficult to see in the dark and at the rocky bottom where it usually swims.

Third Stage: Reproductive Isolation
Reproductive isolation is when groups of a same species are reunited and cannot interbreed with each other anymore, so they are now identified as different species.
Reproductive isolation's role in evolution is too separate species into new ones so they have the best adaptations for their required environment or habitat.
Reproductive isolation occurs in sharks because sharks live in every ocean in the world, examples of different types of sharks are the hammerhead, bull, and great white sharks.
