Changes in the environment can lead to variations in organisms. Environmental changes, such as natural disasters, climate change, or human activities, can alter an organism's habitat and resources. This can result in different selection pressures on the population, leading to changes in their genetic makeup and ultimately causing variations within the population. These variations can have adaptive or maladaptive effects on the organisms, shaping their evolution over time. Thus, there is a direct relationship between changes in the environment and variations in organisms.
