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.
The answer is chromosomes. The chromosome contains the DNA nuclei. It contains all the genetic material of the parents.It is often duplicated in the cell metaphase of the cell division. Chromosomes differ from one organism to another. They are often visible under the microscope.
