why is variation not necessarily beneficial for the individual?
Please answer with respect to the individual only.
Answers
Variations allows organisms to exist in diverse habitats or niches. In absence, a species may remain restricted to particular area. If this area gets drastically altered due to various natural or man made causes, the species may be wiped out. However, if some variations are present in few individuals, it would help them to colonise other habitats & survive. But if variations are present in single organism, there would be a very little chance for it to survive.
♤ 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.
