The given question is seems it lacks some information, however, on the best knowledge of the provided information the correct answer would:

The change in the population of each organism is due to the evolution process that takes place because of changes in the environment in order to survive.

The changes in the genetic material of a particular population occur over a long period of time, the cause of this change is the process called evolution.

  • Evolution exhibits the adaptations that took place in organisms to their environmental changes that lead to altered genes, novel characteristics, and new species.
  • changes in genetic variability and changes in allele frequencies over time
  • natural selection is the cause of evolution that occurs in organisms that are more likely to survive and reproduce
  • random fluctuations in allele frequencies in a population called genetic drift

Thus, the correct answer is - evolution.
