WebSpeciation is the process by which new species form. It occurs when groups in a species become reproductively isolated and diverge.

In both cases, natural selection occurs because certain traits provide an advantage in a particular environment, allowing individuals with those traits to survive and reproduce more successfully. WebMutation followed by natural selection results in a population with darker colouration.
