Answer:
A. Evolution
Explanation:
Natural processes like speciation create variation in species, making them have biodiversity and a diverse gene pool.
Gradualism also allows for species to change gradually over time.
Both of these processes allow for evolution to occur, as speciation can create more favorable traits that will be passed down with the process of gradualism.
So, the correct answer is A, evolution.
