Answer :

Final answer:

Genetic variations that enhance survival are mainly due to mutations.


Explanation:

Genetic variations that lead to different traits improving an organism's ability to survive are primarily caused by mutations. Mutations are random changes in an organism's genes that can result in new beneficial traits. These mutations, if advantageous, can be passed on to offspring, increasing the likelihood of survival and the evolution of a population.
