Question

why is varition beneficial to the species but not necessarily for the individual

Answer 1

variation is necessary for species that's because of survival and other factors such as genetics and environmental factors minor and major evolutionary factors,saltations but if there is a variation between EVERY individual there won't be any reproductive scenario as only same species can interbreed if every one would be different there would be no scope for survival of any of them as they can't make new young ones that's why you don't see variation among the same individual, yet we differ from others by our genomic data and some inheritance factors also acquired factor like having a bad habits which might not be in someone else. that's why you don't have variation in the individual !

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.
