Imagine you are a scientist observing rats in the wild. As the rats produce, rats born with white fur slowly begin to outnumber rats with black fur. And three to five sentences provide two or more different explanations of why the rats white fur might be outnumbering the rats with black hair
1 answer
One possible explanation is that the white fur provides better camouflage in the environment where the rats live, making them less visible to predators and giving them a survival advantage. Another explanation could be that white fur is a genetically dominant trait, and as more white-furred rats mate and pass on their genes, the population gradually shifts towards white fur.
