They both result in a particular allele rising in frequency in the population over time. They are different in that natural selection will only cause an allele to rise in frequency if that allele provides individuals with an increased relative fitness. Artificial selection can be used to cause a rise in frequency of alleles which do not provide individuals with increased relative fitness.
