Question

Why is variation beneficial to the species but not necessarily for the individuals?

Answer 1

Variations are necessary for organic evolution. These variations may be environmental or genetic. Many times a particular variation may occur only in a few organisms of a specie because it may not be beneficial for the survival of that species but if it is, then it will be passed on to the progeny and will be observed in the whole species.

Answer 2

♤ 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.
