Respuesta :
The answer is; B
Natural selection acts on the variability of genotypes in a population. As the environment changes, the alleles in the population that confer an advantage in the changing environment are preserved as the disadvantageous alleles are weeded out over generations. This way the population changes through the process of speciation.
The process of Speciation causes a favorable adaptations to build up in a population over many generations due to long-term environmental change
What is speciation?
Speciation refers to creation of new and distinct species in the course of evolution.
Generally, as the environment changes, the alleles in the population that confer an advantage in the changing environment are preserved as the disadvantageous alleles are weeded out over generations.
Thus, the population changes through the process of speciation.
Therefore, the Option B is correct.
