Variation 1 is likely becoming more common due to the advantages it confers in the rats' specific environment, which could include factors such as improved camouflage, better foraging abilities, or increased resistance to predators or disease. As individuals with variation 1 are more successful at surviving and reproducing, they pass down their traits to subsequent generations, leading to an increase in the frequency of this variation within the population over time. This process is a key aspect of natural selection, where advantageous traits become more prevalent due to differential survival and reproduction among individuals.
