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.
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.
what variation would help a land survive in long lasting droughts

The evolution of a species is influenced by factors such as natural selection, genetic variation, environmental changes, and reproductive success. These factors can lead to adaptations that help a species survive and thrive in its environment over time.
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.
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.
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.
there is variation among the members.
Because on very, very rare occasions the variation may be helpful
Variation within a species creates a diverse gene pool, allowing some individuals to possess traits that are better suited for the new environment. This increases the likelihood that at least some individuals will survive and reproduce. Over time, these advantageous traits can become more prevalent in the population through natural selection.
