The most direct result of natural selection on a population is a change in the frequency of certain alleles in the population. This occurs as individuals with advantageous (or disadvantageous) traits have a greater (or lesser) likelihood of survival and reproduction, passing on their traits to the next generation. Over time, this can result in a noticeable shift in the frequency of certain alleles in the population. New alleles may also arise through mutation, but this is not the most direct result of natural selection. Proteins losing some functions and members of the population reproducing more rapidly are not direct results of natural selection at all.
