Variations may result in subsequent change of the body design of the organism.
it may positively and negatively affect the organism . A variant may also be changed according to the niche it occupies individually.this may affect the sustainance of the organism. But as the organism reproduce,new variants originate and accumulation of variations occur over time which is beneficial for a species
For example
certain bacteria may be killed in a heat wave but some variants resistant to heat will survive due to VARIATIONS in them .

♤ A species include large no. Of individuals of same kind. All the organisms of a species have similar body design and well adapted to the place.
♤ If there is a variation arise from the individual it might not be beneficial to it, even this variation may lead to the death of the individual.
♤ but the variation may be beneficial if the species faces a drastically altered condition.
♤ In this condition the population may wiped out completely but of some variation are there few individual can survive and thus variation is beneficial for the species.
