Which of the following statements is TRUE about natural selection?
a. Even if natural selection acts on a trait, it is possible for evolution to not occur in the population.
b. Natural selection is random.
c. Natural selection results in individuals that are adapted to future conditions.
d. All of the above.
e. None of the above.
Answer: a. Even if natural selection acts on a trait, it is possible for evolution to not occur in the population.
Natural selection is a selective process which sorts out some genes and phenotype characteristics in the population. It benefits those possessing the advantaged genotypes hence the increase of the Genotype frequency within the next generations. Nonetheless, if the variation is restricted or if there is no heritable variation for the relevant character in the population, there would be no evolution even where this occurs through natural selectiveness. It is important to know that the process of natural selection can only act on the variation that has been present in the population during that period. Natural Selection does not make new variations or adaptations for future scenarios rather it works on the already existing variations which are more suitable in the current environment.
