Creation of variation occurs in a species and help in the survival to species as the most suitable or favorable character pass next generation and under unfavorable condition only the most fit organism survive and help in continuation of the species.
It causes diversity and variation amongst a population
what variation would help a land survive in long lasting droughts
Because on very, very rare occasions the variation may be helpful
Advantage- On the species level, variation allows a population to maintain a healthy diversity, allowing it to cope with changing circumstances.Disadvantage- On the individual level, variation may lead to detrimental changes as well as neutral and beneficial changes.

As each new generation is produced, genetic variation may be introduced into a population. The more genetic variation in a population, the more likely it is that some individuals might have traits that will be advantageous if the environment changes.

The differing traits provided by variation mean that at least some groups of the species may be better prepared to survive.

A "variation" is a genetic feature expressed in some physical, physio chemical or behavioral manner by a living organism that is not present in the general population of the species to which that living organism belongs. If that variation advantages that animal as compared to others of that species then the likelihood is that that animal will breed more successfully, potentially passing on that variation to its offspring. Slowly variations accumulate and one species changes into a new species - this is called evolution.
To make a long answer short, when a variation helps an animal survive in its habitat, that animal will become more successful than it used to be, and enough variation can lead to a new species.
Hats off to Sir Charles Darwin for his theory of evolution! Variations are very important to species. Some of the variations are more suitable for the species to survive. You get new species with time by selection of the better ones.
When environmental conditions change it is more likely that at least some members of a species will survive if there is variation among the members.
Reproduction does not help a species to survive, it allows for a species to survive by replacing the ageing population. Without reproduction a species would cease to exist within 1 generation. By reproducing, the species adds to it's population, which helps the species to survive for a longer period of time, because they will not be killed off as easy and will not go extinct:)
