Changes in the environment can act on existing variations in a population and influence the fitness of an organism. This can result in certain traits becoming more advantageous while others become less advantageous, leading to natural selection and adaptation within a population. Additionally, changes in the environment can also cause new variations to appear through processes such as mutation and genetic recombination. Therefore, changes in the environment and variations in a population are closely interconnected and can have a significant impact on the evolution and survival of a species.
