The correct answer is D. Polar bears having white fur is an example of an effect of natural selection.
To understand why, let's first understand what natural selection is. Natural selection is the process in which individuals with certain inherited traits are more likely to survive and reproduce, thus passing on their traits to future generations. This process leads to the gradual adaptation of populations to their environment over time.
In the case of polar bears having white fur, this is an example of natural selection at work. Polar bears live in Arctic environments where snow and ice are predominantly white. The white fur of polar bears helps them blend into their surroundings, making it easier for them to hunt and capture prey. At the same time, this white fur provides them with camouflage, helping them evade potential predators.
Over time, polar bears with white fur are more successful in finding food and avoiding predation compared to bears with darker fur. As a result, these individuals are more likely to survive and reproduce, passing on the genetic variation for white fur to future generations.
In summary, polar bears having white fur is an example of an effect of natural selection because it represents an adaptation that helps them survive and reproduce in their specific environment.
